The TIDA-00483 reference design showcases a 4-20mA current loop subsystem that measures the surrounding environment and communicates temperature, humidity, and ambient light over the loop. Its compact footprint houses all sensors, filters, and control circuitry to compute and transmit sensor data. Intended for process measurement in factory automation, field transmitters, and building automation, the design runs sensors, MCU, and communication modules on less than 3.5 mA from the current loop power.

  • Transmit Two Variables Simultaneously: Reduce cabling and installation costs by sending two variable parameters at once over a 4-20mA current loop
  • Expand Sensor Parameters: Add more sensor data via an FSK-modulated digital data stream
  • Efficient FSK Generation: Dual op-amp 4th order Butterworth filter reduces component count
  • Power-Efficient MCU: Ultra Low power MSP430 consumes less current, allowing more for sensors in the loop
