ADS8866IDGSR

The 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 supports unipolar single-ended analog inputs in the range of -0.1 V to V_REF + 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. No Separate LDO Required for the ADC Supply
