I am new in this forum. I am considering to use attached CN0357 board to read Oxygen Sensor 3 Electrode. But the Biasing current required -600mV. I have read in this fourm that i need to remove ADR3412 and give biasing voltage instead. my question is that should i give -600mV on this Vref pin. i would be pleased if you could guide me to solve the issue at this initial stage.
Thanks in advance.
