I am trying to measure the current flowing to/from a battery by using two INA169. I have already made a one way current measurement with one INA169, and 0.02 ohm shunt resistor and a 50k external resistor, which works perfectly with a output of 1V per A.
I would like to have an output between 0 and 5V. 0V output when the battery is charging with 2.5A, 2.5V output when no current is flowing to/from the battery, and 5V output when 2.5A is flowing from the battery.
I am trying to use two op-amps, but i have no prior experience with electronics, so i found a webpage with an example of what i am trying to do with the op-amps:
I have attached a image of a schematic what i have tried to do, but the op-amp part doesn’t work. Can anyone tell me if this setup would work?
