TIDA-00165, Small form Factor, 2-Wire 4 to 20mA Current Loop RTD Temperature Transmitter Reference Design. This is a reference design for a robust, low power, precise and long-term stable 2-wire loop powered 4 to 20mA current output temperature transmitter. It uses RTD temperature sensor with 4 to 20mA current loop transmitter. It also explains sensor signal conditioning, ratiometric measurement technique, recommended software flow, calibration, sensor linearization, PCB layout and other practical design considerations. Furthermore, external protection circuitry is deployed in-place for compliance with regulatory IEC61000-4 standards-EFT, ESD and Surge requirements
