1 Overview

The AFE882H1 16-bit digital-to-analog converter (DAC) is a highly-integrated, high-accuracy, and extremely low-power device with voltage-outputs designed for HART® enabled factory automation and control applications. The AFE882H1 includes most of the components required to construct an analog output module with voltage and current outputs. These components include a 16-bit highly accurate DAC, a HART FSK modem, an internal 10-ppm/°C voltage reference, and an internal diagnostic ADC. An XTR305 converts the AFE882H1 output to output voltage driver for ±11 V and an output current driver for –25 mA to +25 mA.
