I use an INA296B3 to sense an high side over current according the following circuit:
The measurements with a static current of +20A through the shunt resistor cause an input voltage differential of +10mV (IN+ to IN-).
The voltage raise at the output of the current sense amplifier is +600mV instate of the expected +500mV.
Measurement with negative currents, show the same voltage gain of 60V/V.
Why is the amplifier gain 60V/V instate of 50V/V?
