N-Channel INA196_x 4-20 mA Current Loop Receiver Sensor Interface


I want to use the INA196_2 Channel module. Could someone clarify for me:

  • What is the function of the INA196 Current Shunt Monitoring chip?
  • What is the value and specification of the shunt resistor (i.e. tolerance, temperature coefficient)?
  • The specification refers to a 16V supply. I presume I can use this to power the sensor?

Many Thanks



  1. INA is a current to Voltage converter. This voltage is read by the on board ADC1115.
  2. The value is 4.99Ohm and tolerance is 1%. temperature range is -40’C to 85’C.
  3. Yes, this 16V will power up the sensor.

Let me know if you have any questions.
