The ADS101S02 and ADS111S02 (ADS1x1S02) are precision, low-power, SPI-compatible, 12- and 16-bit analog-to-digital converters (ADCs). The ADS1x1S02 integrate a low-drift voltage reference, oscillator, a programmable gain amplifier (PGA), and high-accuracy temperature sensor. These features, along with the device wide power supply range from 1.74V to 5.5V, are useful for power- and space-constrained, sensor measurement applications.

The ADS101S02 and ADS111S02 perform conversions at data rates up to 6 and 4kSPS, respectively. The PGA offers gain settings from 1/6 to 16, allowing precise large- and small-signal measurements using the internal 1.024V reference. The ADS1x1S02 feature an input multiplexer (MUX) that allows four single-ended measurements, three differential measurements using AIN3 as a common reference, or two independent differential input pairs.
