Texas Instruments ADS886x 16-Bit SAR Analog-to-Digital Converters are 16-bit, single-ended input, analog-to-digital converter (ADC). The device operates with a 2.5V to 5V 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 offers an SPI-compatible serial interface that also supports daisy-chain operation for cascading multiple devices. An optional busy-indicator bit (available for ADS8860, ADS8861, ADS8862, ADS8863, ADS8864, ADS8865 only) makes synchronizing with the digital host easy. Device operation is optimized for very low-power operation. Power consumption directly scales with speed. This feature makes the ADS886x excellent for lower-speed applications.
