OPA187 Zero-Drift Op-Amp

Texas Instruments' rail-to-rail output, low-power 36 V op-amp is unity-gain stable and free from unexpected output phase reversal

Image of Texas Instruments' OPA187 Zero-Drift Op AmpTexas Instruments' OPA187 op-amp uses auto-zeroing techniques to simultaneously provide low offset-voltage (1 µV), and near zero-drift over time and temperature. The miniature, high-precision, low-quiescent current amp offers high-input impedance and rail-to-rail output swing within 5 mV of the rails into high-impedance loads. The input common-mode range includes the negative rail. Either single or dual supplies can be used in the range of 4.5 V to 36 V (±2.25 V to ±18 V).

The OPA187 is available in micro-sized 8-pin VSSOP, 5-pin SOT-23, and 8-pin SOIC packages. The device is specified for operation from -40°C to +125°C.
