Overview
The ADS7960SRHBR is a part of the ADS79xx family of analog-to-digital converters (ADCs) produced by Texas Instruments. This device is a 12-bit, 1-MSPS (mega-samples per second), 12-channel ADC that features a capacitor-based successive approximation register (SAR) converter with inherent sample and hold. It is designed for high-speed data acquisition and offers low power consumption, making it suitable for battery-powered and isolated power-supply applications.
