Overview
The ADS1224IPWT is a 24-bit, delta-sigma analog-to-digital (A/D) converter produced by Texas Instruments. It is designed for high-resolution measurements and is particularly suited for portable systems and other space-saving, power-constrained applications. The device features a 4-channel differential input multiplexer, a high-impedance input buffer, and a simple 2-wire serial interface. It operates within a temperature range of -40°C to 85°C and is packaged in a 20-pin TSSOP (PW) package.
