Overview
The ADS7953SBDBTG4 is part of the ADS79xx family of analog-to-digital converters (ADCs) produced by Texas Instruments. This device is a 12-bit, 16-channel, single-ended ADC with a serial interface. It is designed for high-speed data acquisition and features a capacitor-based successive approximation register (SAR) A/D converter with inherent sample and hold capabilities. The ADS7953 is suitable for a wide range of applications due to its low power consumption, making it ideal for battery-powered and isolated power-supply systems.
