Overview
The ADS7952SBRHBR is a 12-bit, 1 MSPS (Mega Samples Per Second), 12-channel, single-ended analog-to-digital converter (ADC) produced by Texas Instruments. It is part of the ADS79xx family, which includes pin-compatible multichannel ADCs with resolutions of 12, 10, and 8 bits. This device is designed for low power consumption, making it suitable for battery-powered and isolated power-supply applications. The ADS7952SBRHBR features a capacitor-based SAR (Successive Approximation Register) A/D converter with inherent sample and hold, and it operates within a wide analog supply range of 2.7 to 5.25 V and an I/O supply range of 1.7 to 5.25 V.
