In Fig3, there is a problem with the linearity of the INA198 device output.
Q1> The measured current was tested in the Current Shunt Amplifer (INA198).
However, when the load is changed to 5V, the output voltage of the INA198 read by the ADC is not linearity.
Small current value due to fluctuation in 100 ~ 50 ohm load variable resistance value
And the current value of 50 ohm to 5 ohm is large.
Is there any way to correct non linearity?
