Description

General part information

ADS7957-Q1 Series

The ADS79xx is a 12-, 10-, 8-bit pin compatible multichannel analog-to-digital converter family. The device comparison table shows all twelve devices from this product family.

The devices include a capacitor based SAR A/D converter with inherent sample and hold.

The devices accept a wide analog supply range from 2.7 V to 5.25 V. Very low power consumption makes these devices suitable for battery-powered and isolated power-supply applications.
