AD694AQ - Brand New Analog Devices Sensor and Detector Interfaces
-
Description
The AD694AQ is a monolithic current transmitter designed for use in process control applications. It accepts high level signal inputs and converts them to a standard 4-20 mA current loop, which can be used to control valves, actuator, and other devices. The input signal is buffered by an input amplifier, allowing for scaling or buffering of the output from a current mode DAC. The AD694AQ offers precalibrated input spans of 0 V to 2 V and 0 V to 10 V, with the option to program other spans using external resistors.
