For current measurement, I'd rather use a Hall sensor. But to measure the signal from that sensor a sensitive opamp is needed, and your comment applies :)

- blackguardx 2y agoUsing Hall-effect sensors to measure current isn’t that common when currents are in the uA to mA range. I’ve also never seen them used even for Amp range measurements when the application is purely on-board power supply meaurement.
- nine_k 2y agoThe example uses 5A. For mA range, of course not.
- kevin_thibedeau 2y agoHigh current lab supplies routinely use current shunts for their self-measurement.
