 +===== OVERVIEW =====
  
 The circuit is a 4 mA-to-20 mA current loop transmitter for communication between a process control system and its actuator. Besides being cost effective, this circuit offers the industry’s low power solution. The 4 mA-to-20 mA current loop has been used extensively in programmable logic controllers (PLCs) and distributed control systems (DCS’s), with digital or analog inputs and outputs. Current loop interfaces are usually preferred because they offer the most cost effective approach to long distance noise immune data transmission. The combination of low power  [[http://www.analog.com/AD8657|AD8657]]  dual op amp,   [[http://www.analog.com/AD5641|AD5641]] DAC, and [[http://www.analog.com/ADR02|ADR02]] reference allows more power budget for higher power devices, such as microcontrollers and digital isolators. The circuit output is 0 mA to 20 mA of current. The 4 mA to 20 mA range is usually mapped to represent the input control range from the DAC or micro-controller, while the output current range of 0 mA to 4 mA is often used to diagnose fault conditions. The circuit is a 4 mA-to-20 mA current loop transmitter for communication between a process control system and its actuator.
