The ADS8329 is a low-power, 16-bit, 1-MSPS analog-to-digital converter (ADC) with a unipolar input. The device 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 programmable option of 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.

These converters are available in 4 × 4 QFN and 16-pin TSSOP packages, and are fully specified for operation over the industrial -40°C to +85°C temperature range.
