7 Parameter Measurement Information
7.1 Light Source Positioning and Uniformity
The OPT101 is tested with a light source that uniformly illuminates the full area of the integrated circuit, including
the op amp. Although the silicon of integrated circuit (IC) amplifiers is light-sensitive to some degree, the OPT101
op amp circuitry is designed to minimize this effect. Sensitive junctions are shielded with metal, and the
photodiode area is very large relative to the op amp input circuitry.
If the light source is focused to a small area, be sure that it is properly aimed to fall on the photodiode. A
narrowly-focused beam falling only on the photodiode provides improved settling times compared to a source
that uniformly illuminates the full area of the die. If a narrowly-focused light source misses the photodiode area
and falls only on the op amp circuitry, the OPT101 does not perform properly. The large 0.09-in × 0.09-in (2.29
mm × 2.29 mm) photodiode area allows easy positioning of narrowly-focused light sources. The photodiode area
is easily visible because the area appears very dark compared to the surrounding active circuitry.
The incident angle of the light source also effects the apparent sensitivity in uniform irradiance. For small incident
angles, the loss in sensitivity is simply due to the smaller effective light gathering area of the photodiode
(proportional to the cosine of the angle). At a greater incident angle, light is diffracted and scattered by the
package. These effects are shown in Figure 5.

8 Detailed Description
8.1 Overview
The OPT101 is a large-area photodiode integrated with an optimized operational amplifier that makes the
OPT101 a small, easy-to-use, light-to-voltage device. The photodiode has a very large measurement area that
collects a significant amount of light, and thus allows for high-sensitivity measurements. The photodiode has a
wide spectral response with a maximum peak in the infrared spectrum, and a useable range from 300 nm to
1100 nm. The wide power-supply range of 2.7 V to 36 V makes this device useful in a variety of architectures;
from all-analog circuits to data conversion base circuits. The on-chip voltage source keeps the amplifier in a good
operating region, even at low light levels.
The OPT101 voltage output is the product of the photodiode current times the feedback resistor, (IDRF), plus a
pedestal voltage, VB, of approximately 7.5 mV introduced for single-supply operation. Output is 7.5 mV dc with
no light, and increases with increasing illumination. Photodiode current, ID, is proportional to the radiant power, or
flux, (in watts) falling on the photodiode. At a wavelength of 650 nm (visible red) the photodiode responsivity, RI,
is approximately 0.45 A/W. Responsivity at other wavelengths is shown in Figure 1. The internal feedback
resistor is laser trimmed to 1 MΩ. Using this resistor, the output voltage responsivity, RV, is approximately 0.45
V/μW at 650-nm wavelength.
See Figure 2 for the response throughout a wide range of radiant power in microwatts. Figure 3 shows the
response throughout a wide range of irradiance in watts per square meter.

8.3 Feature Description
8.3.1 Dark Performance
The dark errors in the Electrical Characteristics table include all sources. The dominant source of dark output
voltage is the pedestal voltage applied to the noninverting input of the op amp. This voltage is introduced to
provide linear operation in the absence of light falling on the photodiode. Photodiode dark current is
approximately 2.5 pA, and contributes virtually no offset error at room temperature. The bias current of the op
amp summing junction (negative input) is approximately 165 pA. The dark current is subtracted from the amplifier
bias current, and this residual current flows through the feedback resistor creating an offset. The effects of
temperature on this difference current are seen in Figure 10. The dark output voltage is trimmed to zero with the
optional circuit shown in Figure 17. Use a low-impedance offset driver (op amp) to drive pin 8 (Common)
because this node has signal-dependent currents.

Feature Description (continued)
8.3.2 Feedback Network and Dynamic Response
The OPT101 features a feedback network for optimal dynamic response. The dynamic response of the OPT101
is dominated by the feedback network and op amp combination. Using the internal 1-MΩresistor, the dynamic
response of the photodiode and op amp combination can be modeled as a simple RC circuit with a –3-dB cutoff
frequency of approximately 14 kHz. The R and C values are 1 MΩand 11 pF, respectively. To improve the
frequency response, use external resistors with less than 3-pF parasitic capacitance. An external 1-MΩresistor
used in the configuration shown in Figure 19 creates a 23-kHz bandwidth with the same 106 V/A dc
transimpedance gain. This increased bandwidth yields a rise time of approximately 15 μs (10% to 90%). Dynamic
response is not limited by op amp slew rate, as demonstrated in Figure 13 and Figure 14, showing virtually
identical large-signal and small-signal response.
Dynamic response varies with feedback network value, as shown in Figure 4. Rise time (10% to 90%) varies as
a function of the –3-dB bandwidth produced by the feedback network value shown in Equation 1:
tr= 0.35 / fC
where
• tris the rise time (10% to 90%)
• fCis the –3dB bandwidth (1)
8.3.2.1 Changing Responsivity
To set a different voltage responsivity, connect an external resistor, REXT. To increase the responsivity, place this
resistor in series with the internal 1-MΩresistor (Figure 18), or replace the internal resistor with an external
resistor by not connecting pin 4 (Figure 19). The second configuration also reduces the circuit gain below 106
V/A when using external resistors that are less than 1 MΩ.

(1) May require 1 kΩin series with pin 5 when driving large capacitances.
Applications using a feedback resistor significantly larger than the internal 1-MΩresistor require special
consideration. Input bias current of the op amp and dark current of the photodiode increase significantly at higher
temperatures. This increase combined with the higher gain (RF> 1 MΩ) can cause the op amp output to be
driven to ground at high temperatures. If this problem occurs, use a positive bias voltage applied to pin 8 to make
sure that the op amp output remains in the linear operating region when the photodiode is not exposed to light.
Alternatively, use a dual power supply. The output may be negative when sensing dark conditions. Use the
information discussed in the Dark Performance section and Figure 10 to analyze the desired configuration.
8.3.3 Noise Performance
Noise performance of the OPT101 is determined by the op amp characteristics, feedback network, photodiode
capacitance, and signal level. Figure 11 shows how the noise varies with RFand measured bandwidth (0.1 Hz to
the indicated frequency), when the output voltage minus the voltage on pin 3 (–V) is greater than approximately
50 mV. Below this level, the output stage is powered down, and the effective bandwidth is decreased. This
decreased bandwidth reduces the noise to approximately 1/3 the nominal noise value of 300 μVrms, or 100
μVrms. This decreased bandwidth enables a low-level signal to be resolved.
To reduce noise and improve the signal-to-noise ratio, filter the output with a cutoff frequency equal to the signal
bandwidth. In addition, output noise increases in proportion to the square root of the feedback resistance, while
responsivity increases linearly with feedback resistance. To improve the signal-to-noise ratio performance, use
large feedback resistance, if decreased bandwidth is acceptable to the application.

The noise performance of the photodetector is sometimes characterized by noise effective power (NEP), the
radiant power that produces an output signal equal to the noise level. NEP has the units of radiant power (watts),
or W/√Hz to convey spectral information about the noise. Figure 12 illustrates the NEP for the OPT101.
8.3.4 Linearity Performance
The photodiode is operated in the photoconductive mode so the current output of the photodiode is very linear
with radiant power throughout a wide range. Nonlinearity remains less than approximately 0.05% for photodiode
currents less than 100-μA. The photodiode is able to produce output currents of 1 mA or greater with high radiant
power, but nonlinearity increases to several percent in this region.
This very linear performance at high radiant power assumes that the full photodiode area is uniformly illuminated.
If the light source is focused to a small area of the photodiode, nonlinearity occurs at lower radiant power.
8.3.5 Capacitive Load Drive
The OPT101 is capable of driving load capacitances of 10 nF without instability. However, dynamic performance
with capacitive loads may improve by applying a negative bias voltage to pin 3 (–V, shown in Figure 20). This
negative power-supply voltage allows the output to go negative in response to the reactive effect of a capacitive
load. An internal JFET connected between pin 5 (output) and pin 3 (–V) allows the output to sink current. This
current sink capability is also useful when driving the capacitive inputs of some analog-to-digital converters that
require the signal source to sink currents up to approximately 100 μA. The benefits of this current sink are shown
in Figure 15 and Figure 16. These figures compare operation with pin 3 (–V) grounded and connected to –15 V.
Figure 20. Bipolar Power-Supply Circuit Connections
Because of the architecture of this output stage current sink, there is a slight increase in operating current when
there is a voltage between pin 3 (–V) and the output. Depending on the magnitude of this voltage, the quiescent
current increases by approximately 100 μA, as shown in Figure 8.
8.4 Device Functional Modes
The OPT101 has a single functional mode and is operational when the power-supply voltage is greater than 2.7
V. The maximum power supply voltage for the OPT101 is 36 V.

9.2 Typical Applications
9.2.1 Color and Reflective Wavelength Tester
A common application for the OPT101 is testing physical materials. Information can be gained about a test
material by determining the optical reflection, transmission, or absorption properties at particular wavelengths.
These test materials can be solid objects, biological or chemical liquids, or any other type of material.
For an intuitive example, this application for OPT101 tests red, green, and blue reflective color properties of a
variety of test materials. This application is not intended to match the color standards as defined by the
Commission Internationale de l'Eclairage (CIE), but to illustrate a generic optical wavelength-specific test
technique. Different applications can test for different wavelengths, including invisible ultraviolet or infrared
wavelengths, that are appropriate for the objective of that application.

9.2.1.2 Detailed Design Procedure
This design illuminates a test material with specific wavelengths, and measures the resulting reflection. Choose
an RGB LED that sequentially creates individual red, green, and blue wavelengths. Red material has a strong
reflection of red wavelengths, and a weaker reflection of green and blue wavelengths. Green and blue materials
follow a similar pattern, reflecting the respective primary color wavelengths stronger than other color
wavelengths.
Design a fixture with a chamber that allows the RGB LED to illuminate the test material and allows the OPT101
to receive the resulting reflection, as shown in Figure 22. Design the chamber to keep out ambient light from the
room. Line the chamber with a matte black foil so that the chamber walls absorb as much light as possible. The
matte black foil helps the OPT101 sensor measure reflections primarily from the test material and only minimally
from the chamber walls. Design a baffle structure between the RGB LED and the OPT101 sensor so that light
does not transmit directly from the RGB LED to the OPT101 sensor without reflecting off of the test material.
Place an additional enclosure over the chamber to enhance the isolation from any light in the room.
Drive the OPT101 power supply pin, VS, with a 5-V power supply, and measure the output pin voltage with a
voltmeter. This voltmeter can easily be replaced with an ADC.
Choose LED drive currents for each of the RGB LEDs. Throughout this procedure, either drive each LED with
this specific chosen current, or do not drive the LED at all. Choose an LED drive current that equalizes the power
dissipation (the drive current times the forward-biased voltage drop across each LED). This equal power
dissipation minimizes thermal transient settling time when switching between the LEDs. This equal power
dissipation is not a requirement if test speed and settling time are not an issue for the application.
Calibrate the fixture by measuring a standard white card as a test material. Drive the red LED, and record the
resulting voltage from the OPT101. Repeat this procedure with the green and blue LEDs.
Next, measure a test material with the same procedure used for the white card. Normalize the results by dividing
the test material result by the white card result for each LED. Determine the color of the object by selecting the
largest of the three LED normalized measurements. Perform an additional normalization step for data clarity by
dividing each of the three LED measurements by the largest of the three measurements.

9.2.1.3 Application Curves
The following figures show that the colors of the test materials sorted properly, as expected. The red test
materials all showed a stronger reflection for red LED than the green and blue LEDs. The results are plotted in
four groups: red (Figure 23, blue (Figure 24), green (Figure 25), and neutral color (Figure 26). The application
clearly identifies the primary color of each test material. When the color is neutral, then the red, green, and blue
test results are very similar to each other, as expected (within 10% of each other).
The red results had the most contrast. The green results had the least contrast. These results are likely different
because the red LED has the least spectral overlap with the green and blue LEDs. The green LED has the
widest spectral content. If more contrast is required, try LEDs (or other light sources) with more-narrow
spectrums.

9.3 Dos and Don'ts
As with any optical product, special care must be taken into consideration when handling the OPT101. Although
the OPT101 has low sensitivity to dust and scratches, proper optical device handling procedures are still
recommended.
The optical surface of the device must be kept clean for optimal performance in both prototyping with the device
and mass production manufacturing procedures. Tweezers with plastic or rubber contact surfaces are
recommended to avoid scratches on the optical surface. Avoid manipulation with metal tools when possible. The
optical surface must be kept clean of fingerprints, dust, and other optical-inhibiting contaminants.
If the device optical surface requires cleaning, use deionized water or isopropyl alcohol. A few gentile brushes
with a soft swab are appropriate. Avoid potentially abrasive cleaning and manipulating tools and excessive force
that can scratch the optical surface.
If the OPT101 performs less than optimally, inspect the optical surface for dirt, scratches, or other optical
artifacts.
Any light falling on the op amp circuitry area must be uniform; see the Parameter Measurement Information
section for more information about light uniformity.

10 Power-Supply Recommendations
The OPT101 is designed to operate from an input voltage supply range between 2.7 V and 36 V. Make sure the
power-supply input is well regulated. Place a 0.01-µF to 0.1-µF bypass capacitor with low-impedance, short
connections between VS(pin 1) and –V (pin 3). If –V (pin 3) is not connected to Common (pin 8), place an
additional bypass capacitor between VS(pin 1) and Common (pin 8).
11 Layout
11.1 Layout Guidelines
Make all power connections with short, low impedance connections.
Depending on the application, the design might benefit from having the OPT101 mounted to the opposite side of
the board as the other electrical components. Keeping the optical sensor side free from extra components allows
for easier mounting of any required optical-mechanical structures around the OPT101.
11.2 Layout Example
The following example shows an external feedback network (R2 and C2) that bypasses the internal feedback
network, similar to Figure 19. This example also shows an external feedback network (R1, C1) in series with the
internal feedback network, similar to Figure 18. To use only the internal feedback network, load R1 or C1 with a
short circuit. This example allows for three different configurations with the same layout. Do not load R1, C1, R2,
and C2 simultaneously.

12.3 Electrostatic Discharge Caution
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
12.4 Moisture Sensitivity and Soldering
Clear plastic does not contain the structural-enhancing fillers used in black plastic molding compound. As a
result, clear plastic is more sensitive to environmental stress than black plastic. This can cause difficulties if
devices have been stored in high humidity prior to soldering. The rapid heating during soldering can stress wire
bonds and cause failures. Prior to soldering, it is recommended that plastic devices be baked-out at 85°C for 24
hours.
The fire-retardant fillers used in black plastic are not compatible with clear molding compound. The OPT101
plastic packages cannot meet flammability test, UL-94.
