Texas Instruments AFE882H1 | Demoboard TIDA-010982

Field transmitter platform, 4mA to 20mA loop-powered interface reference design

Overview

TopologyDAC
Input voltage8-30 V
IC revisionJANUARY 2026

Description

This reference design gives an example implementation of a 4–20mA interface for 2-wire loop-powered sensors. The design enables evaluation of the AFE881H1 and AFE882H1 in a lower power application-like environment with a 1.8V signal chain. The AFE881H1 and AFE882H1 integrate a high-precision 16-bit digital-to-analog converter (DAC) and a HART® modem. The reference design provides a serial peripheral interface (SPI) and universal asynchronous receiver-transmitter (UART) interface on a pin header to connect to a microcontroller (MCU). This pin header provides 3.3V and 1.8V to power a MCU and a 1.25V reference voltage to be used for an analog-to-digital converter (ADC).

Features

Implementation of 4–20mA loop interface for 2-wire loop-powered sensorComplete 1.8V signal chain allows low power consumption and maintains high accuracyAFE88xH1 16-bit DAC with integrated reference and HART modemMCU interface providing power output (1.8V, 3.3V, 1.25V reference voltage), SPI and UART interface
