Overview
The ADS1210UG4, produced by Texas Instruments, is a precision 24-bit delta-sigma Analog-to-Digital (A/D) converter. This component operates from a single +5V supply and is designed for high dynamic range and low noise applications. It features differential inputs, making it ideal for direct connection to transducers or low-level voltage signals. The ADS1210UG4 includes a programmable gain amplifier (PGA), a second-order delta-sigma modulator, a programmable digital filter, and a serial interface for data transfer. It also supports internal and external reference options and on-chip self-calibration to correct for internal offset and gain errors.
