4-20mA Current Loop D/A Converters

ADI integrated solutions combine both the D/A converter and driver in one chip to provide the required output directly from the digital domain. Analog Devices’ portfolio of leading industrial D/A converters and drivers provides a range of programmable output ranges from standard 4 mA to 20 mA for current loop communication to ±10 V for actuator control. ADI industrial converters offer considerable control functionality and advanced on-chip diagnostics to maximize system uptime, as well as eliminate the need for costly calibration routines needed by some traditional discrete architectures.

HART technology offers a complementary mode of communication to 4 mA to 20 mA that provides additional information in the form of remote diagnostics and system troubleshooting where it can be used to enhance the safety integrity level rating of a system. ADI offers a family of HART modems and 4 mA to 20 mA converters that can be used together to realize a robust, accurate, and HART Foundation registered solution. Our solutions address requirements for both loop and non-loop powered transmitters, and isolated and non-isolated analog I/O cards.
