ADS8866 16-Bit Analog-to-Digital Converters

TI offers the ADS8866 16-bit, 100 kSPS, serial interface, microPower, miniature, single-ended input, SAR analog-to-digital converters

Image of Texas Instruments' ADS8866 16-Bit Analog-to-Digital ConvertersTexas Instruments' ADS8866 is a 16-bit, 100 kSPS, single-ended input, analog-to-digital converter (ADC). The device operates with a 2.5 V to 5 V external reference, offering a wide selection of signal ranges without additional input signal scaling. The reference voltage setting is independent of, and can exceed, the analog supply voltage (AVDD).

The device is SPI-compatible and supports daisy-chain operation for cascading multiple devices.

The device supports unipolar single-ended analog inputs in the range of -0.1 V to VREF +0.1 V.

Device operation is optimized for very low-power operation. Power consumption directly scales with speed. This feature makes the ADS8866 excellent for lower-speed applications.
