Overview
The ADS7816UB is a 12-bit, high-speed, micropower sampling analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed for low power operation and features automatic power down, a synchronous serial interface, and a differential input. The ADS7816UB is suitable for battery-operated systems, remote data acquisition, and isolated data acquisition due to its low power consumption and small size. It is available in various packages, including 8-pin plastic mini-DIP, 8-lead SOIC, and 8-lead MSOP.
