ADS1220IPWR TI Precision ADC | 16-TSSOP | 24-Bit, 2kSPS, Low-Power

Product Overview

The ADS1220IPWR is a precision, 24-bit analog-to-digital converter (ADC) from Texas Instruments, offering a low-power, small-form-factor solution for high-resolution measurement applications. It features a delta-sigma architecture with integrated programmable gain amplifier (PGA), voltage reference, and oscillator, making it ideal for sensor signal conditioning. The device operates from a 2.3V to 5.5V supply and consumes only 120 µA typical current, extending battery life in portable systems. Housed in a 16-pin TSSOP package, it provides a compact footprint for space-constrained designs.
