The circuit detailed in the schematics function is to amplify a voltage across a 30mOhm shunt resistor in phase A and C of a PMSM.

I'm currently having issues calculating the current value of both phases.

Take in consideration that the jumpers are short circuit to the bias resistors on top. (2-3).

Any help is appreciated.

 

Gain is +5 thru NI path, - 5 thru Inv path.
