ADS8331 Overview
The ADS8331 is a low-power, 16-bit, 500-k samplesper-second (SPS) analog-to-digital converter (ADC) with a unipolar, 4-to-1 multiplexer (mux) input. The device includes a 16-bit capacitor-based successive approximation register (SAR) ADC with inherent sample and hold. The ADS8332 is based on the same core and includes a unipolar 8-to-1 input mux.
