Texas Instruments ADS8329IRSATG4

Description
The ADS8329 is a low-power, 16-bit, 1-MHz analog-to-digital converter (ADC) with a unipolar input. It includes a 16-bit capacitor-based SAR ADC with inherent sample-and-hold. The ADS8330 is based on the same core and includes a 2-to-1 input MUX with a programmable option for TAG bit output. Both the ADS8329 and ADS8330 offer a high-speed, wide voltage serial interface and are capable of chain mode operation when multiple converters are used.
