Single-Channel: Isolated: 3-Wire Current Loop Transmitter Reference Design

Description

This single-channel: input-isolated: three-wire current loop transmitter reference design provides a current range of 0 mA to 20 mA while operating on a 24-V supply. The design features a precision digital-to-analog converter (DAC) with an internal reference voltage: integrated three-wire current loop transmitter: and a digital isolator to realize the circuit goals. Protection circuitry is included to pass the IEC61000-4 tests.
