ADS1119IRTER

16-Bit, Low-Power Delta-Sigma ADC with Integrated PGA

Product Description

Product Overview

The ADS1119IRTER is a low-power, high-precision 16-bit delta-sigma analog-to-digital converter (ADC) designed for applications requiring accurate measurement of low-level signals with minimal power consumption. It integrates a programmable gain amplifier (PGA), internal reference, and digital filtering, significantly reducing external component count. With its compact package and I²C-compatible digital interface, the ADS1119 is well suited for battery-powered, portable, and embedded measurement systems.
