ADS1222IPWT TI ADC | 14-TSSOP | 24-Bit, 2-Ch, Low-Power

Product Overview

The ADS1222IPWT is a precision, 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) from Texas Instruments. It offers two differential inputs, an integrated programmable gain amplifier (PGA), and a low-drift voltage reference. Operating from a 2.7V to 5.5V supply, it consumes only 120 μA, making it ideal for low-power industrial and sensor applications. The device communicates via SPI interface and is available in a compact 14-TSSOP package.
