7.1 Overview

The ADS8350, ADS7850, and ADS7250 belong to a family of dual, high-speed, simultaneous-sampling, analog-to-digital converters (ADCs). The devices support pseudo-differential input signals with the input common-mode equal to the reference voltage and the full-scale input range equal to twice the reference voltage. The devices provide a simple serial interface to the host controller and operate over a wide range of digital power supplies.
