Composed of load current high-end INA337 shunt measurement circuit as shown: As shown by INA337 high-end shunt measurement circuit composed of load current. The circuit adopts the sampling resistor Rs series between the source and load, load current IL through Rs will produce a voltage drop, the voltage drop reflects the changes in load current. Will be as input voltage, the voltage drop across the Rs after INA337 amplifier output. Should be paid attention to when selecting Rs in Rs on the formation of the Rail voltage drop cannot exceed supply voltage (maximum) 100 mv. R0, C0, output filter network, can filter out noise circuit output.
