Overview
The ADS1216Y/2K is a precision, wide dynamic range, delta-sigma Analog-to-Digital (A/D) converter produced by Texas Instruments. This 24-bit resolution converter operates from 2.7V to 5.25V supplies and is designed for high-resolution measurement applications. It features eight multiplexed input channels, internal buffering for high input impedance, and burnout current sources for sensor fault detection. The ADS1216Y/2K is ideal for use in smart transmitters, industrial process control, weight scales, chromatography, and portable instrumentation.
