The AD694AQ from Analog Devices is a monolithic current transmitter that drives a standard 4-20 mA current loop, suitable for controlling valves and actuators in process control systems. It accepts high-level signal inputs, which are buffered by an input amplifier that can scale the signal or buffer output from a current mode DAC.
Precalibrated input spans of 0 V to 2 V and 0 V to 10 V are selectable via pin strapping, with other spans programmable using external resistors. The device operates on single or dual supplies with a wide power supply range from 4.5 V to 36 V. The output stage compliance extends to within 2 V of VS, and it includes an open-loop alarm to warn of loop issues.
Active laser trimming ensures high accuracy without additional adjustments. An optional external pass transistor can be used to reduce self-heating errors, extending the operational temperature range. The AD694AQ is specified for an industrial temperature range of -40°C to +85°C.
