This certified reference design implements a 12-bit loop-powered, or 2-wire, transmitter using DAC7311, OPA317 and TL431B. The design includes a protection circuit that provides immunity to the IEC61000-4 test suite. The design also includes a circuit to rectify a reverse polarity supply voltage. The protection circuit and rectifier do not negatively affect the current output performance, resulting in <0.2% total unadjusted error (TUE).
This design is applicable for industrial automation and process control applications requiring a low-cost solution for two-wire data transmission.
