Quick question for the team !! For a current measuring circuit that is capable for (0V to 12V, 0A to 3A), what would the selection of shunt resistor be? Knowing 12V x 3A = 36Watts. Any recommendation of resistors and what will be the ohm value? Thanks, BTFDev

Resistor tolerance for shunt current measuring

Agreed!

At this point we are look for 1% tolerant and TI shunt monitor INA209 could be a good choice.

Any comment?

Thanks, BTFDev
