Texas Instruments ADS8327IBRSARG4

Description
The ADS8327 is a low-power, 16-bit, 500-kHz analog-to-digital converter with a unipolar input. It features a 16-bit capacitor-based SAR A/D converter with inherent sample and hold. The ADS8328 is based on the same core and includes a 2-to-1 input MUX with a programmable option for TAG bit output. Both the ADS8327 and ADS8328 offer a high-speed, wide-voltage serial interface and are capable of chain mode operation when multiple converters are used.
