he power source and the load, the load current IL flows through Rs, the voltage drop reflects the change in load current. The voltage drop on Rs as an input voltage, after INA337 amplifier output. Select the Rs should pay attention to the voltage drop on Rs formation can not exceed the power supply voltage Rail (Max) 100mV. R0, C0, is the output filter network, you can filter out the noise output of the circuit.
