1 Overview
The AFE881H1 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 sensor transmitter applications. The AFE881H1 includes most of the components required to construct a transmitter for 2-wire (loop-powered), 4-mA to 20-mA sensor transmitter applications. 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. To accommodate intrinsic and functional safety concerns, external voltage-to-current conversion and power-regulation are required.
