DAC8742HPBS TI HART Modem | 32-TQFP (5x5) | Low-Power, 1200bps

Product Overview

The DAC8742HPBS from Texas Instruments is a low-power, HART-compliant modem IC designed for industrial process control and smart transmitter applications. It integrates a complete HART physical layer, including modulation, demodulation, and signal conditioning, in a compact 32-TQFP (5x5 mm) package. Operating from a single 2.7V to 5.5V supply, it consumes only 85 µA typical current, making it ideal for loop-powered devices. The device supports Bell 202 standard (1200 bps FSK) and is fully compliant with HART protocol specifications.
