Hi Guys,
I am trying to build a circuit that the MCU can measurement the current consumption of the circuit. I have read a few things and decided to go with the "low side" measurement.
Incidentally I have some BB INA's laying around from my previous project, so I use it as the amplifier of choice.
I am confused that which "Ground" should I connect the amplifier ref. and Voltage ref GND to - the ground of the load (virtual ground) or the ground of the system (0V)?
Most importantly, will the circuit work?
I am more a digital guy than analog - help appreciated. Thank you!
