Hey everyone. I am going to crowd-source this one because I can't seem to find any!
All of the current-sensing op-amps I seem to find are only capable of working with an input voltage (before the sense resistor) of more than 1.6V or so. I need one that can work down to .1V. I can supply the op-amp with a separate power supply (5V or whatever), but I need it to be able to sense currents through a low voltage, but it doesn't seem like there are any!
Help me people! I am working on designing a nice, switching power supply for you folks
