Other Parts Discussed in Thread: INA199
I have used tlv333 to read motor current by differential detection,
but the maximum input impedance in MCU input port is less than 5K,
It’s said that I can eliminate the influence of impedance by REF Potential according to the design of Ina199.Please could you share me what’s the value of REF PIN resistance to the ground or VCC resistor?
In my actual application, the supply voltage is 5V, the magnification is 50 times
