Re: Any current sense amps that can handle 0V on one side of shunt?

Hi there - I'm looking to sense currents going through the three lines
into a brushless motor. The motor will be operated in both directions,
so at some times I'll have something like 49.95 and 50.00 on the two
sides of the shunt resistor, and at other times I'll have 0 and 0.05
on the two sides of the shunt resistor. Are there any current sense
amplifiers that can handle this? Thanks!

that's a tough ask.

non-contact sensors may work better, either current transformers or
hall-effect current sensors.
