Description for the ADS8166

The ADS816x is afamily of 16-bit, 8-channel, high-precision successiveapproximation register (SAR) analog-to-digital converters (ADCs) operating from a single 5-V supplywith a 1-MSPS (ADS8168),
500-kSPS (ADS8167), and 250-kSPS (ADS8166) total throughput.

The input multiplexer supports extended settling time, which makes driving the analoginputs 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 themultiplexer.

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