Product Summary

The AD694ARZ is a monolithic current transmitter that accepts high level signal inputs to drive a standard 4–20 mA current
loop for the control of valves, actuators, and other devices commonly used in process control. The input signal is buffered by

an input amplifier that can be used to scale the input signal or buffer the output from a current mode DAC. Precalibrated input

 spans of 0 V to 2 V and 0 V to 10 V are selected by simple pin strapping; other spans may be programmed with external

resistors.
