The ADS1x2C14 are precision, low-power, 16- and 24-bit, analog-to-digital converters (ADCs) that offer many integrated features to reduce system cost and component count in the most common sensor measurement applications. The devices feature eight analog inputs through a flexible input multiplexer (MUX), a low-noise, programmable gain amplifier (PGA), a programmable low-drift voltage reference, two programmable excitation current sources, an oscillator, and a temperature sensor.

Four speed modes, with programmable output data rates from 20SPS up to 64kSPS, allow to optimize power consumption and noise performance for each application. At output data rates of 20SPS and 25SPS, the integrated digital filter offers simultaneous 50Hz and 60Hz line-cycle rejection with single-cycle settling.
