HART & 4-20mA Loop Interface Devices

Analog Devices loop interfaces offer industrial outputs for 4 mA to 20 mA currents, bipolar and unipolar voltages, and HART output devices.

Our standalone loop interface driver solutions can be mated with our precisions DACs, while ADI integrated solutions combine both the DAC and driver in one chip to provide the required output directly from the digital domain. We also provide a line of HART-compatible modems to directly interface with our loop interface products, for enhanced communication. Our solutions address requirements for both loop and nonloop powered transmitters, and isolated and nonisolated analog I/O cards.
