DAC8741HRGET TI HART Modem | 24-VQFN (4x4) | Low Power, 1.71V-5.5V

Product Overview

The DAC8741HRGET is a low-power, HART-compliant modem from Texas Instruments, designed for industrial process control and smart transmitter applications. It integrates a complete HART physical layer, including a FSK modem and a voltage output DAC, in a compact 24-VQFN (4x4 mm) package. Operating from a single 1.71V to 5.5V supply, it consumes only 85 µA typical current, making it ideal for loop-powered devices.
