Overview
The ADS7816PB is a 12-bit, high-speed, micro-power sampling analog-to-digital converter (ADC) produced by Burr-Brown, now a part of Texas Instruments. This device is designed for low power operation and features automatic power down, making it ideal for battery-operated systems and applications where multiple signals need to be acquired simultaneously. The ADS7816PB uses a synchronous serial interface and supports differential input, enhancing its suitability for remote and isolated data acquisition.
