a FEATURES 4–20 mA, 0–20 mA Output Ranges Precalibrated Input Ranges: 0 V to 2 V, 0 V to 10 V Precision Voltage Reference Programmable to 2.000 V or 10.000 V Single or Dual Supply Operation Wide Power Supply Range: 4.5 V to 36 V Wide Output Compliance Input Buffer Amplifier Open-Loop Alarm Optional External Pass Transistor to Reduce Self-Heating Errors 0.002% Typ Nonlinearity 4–20 mA Transmitter AD694 FUNCTIONAL BLOCK DIAGRAM PRODUCT DESCRIPTION The 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 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. The output stage compliance extends [ … ]
