The ADS816x is a family of 16-bit, 8-channel, high-precision successive approximation register (SAR) analog-to-digital converters (ADCs) operating from a single 5-V supply with 1-MSPS (ADS8168) and
250-kSPS (ADS8166) total throughput.

The input multiplexer supports extended settling time, which makes driving the analog inputs easier. The output of the multiplexer and ADC analog inputs are available as device pins. This configuration allows one ADC driver op amp to be used for all eight analog inputs of the multiplexer. The ADS816x simplifies processing of data with an enhanced channel sequencer, which reduces software complexity.

The ADS816x device family features a digital window comparator with programmable high and low alarm thresholds with hysteresis per analog input channel. The single op-amp solution with programmable alarm thresholds enables low power, low cost, and smallest form factor applications.
