PRODUCT DESCRIPTION\nThe AD694 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 in put 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.FEATURES\n4–20 mA, 0–20 mA Output Ranges\nPrecalibrated Input Ranges: 0 V to 2 V, 0 V to 10 V\nPrecision Voltage Reference\n?
