High Accuracy Loop Powered 4mA to 20mA HART Modem [Copy link]

This reference design provides a solution for loop-powered, high-accuracy field (sensor) transmitters using a HART modem. This design uses some discrete 4mA to 20mA current transmitters, a HART modem, a microcontroller, and power conditioning blocks to implement a smart field transmitter design. This design complies with the HART FSK physical layer specification and is registered with the FieldComm Group.
