Hi, I started an earlier post about an OP-amp, but I wanted to start at the beginning. I want to scale an LCD display linearly with current in a wire so that it 1 A corresponds to a displayed value of 20, 2 corresponds to 40, etc. I have a 0.001Ω shunt, that the current goes through, so I can measure the voltage across the shunt. The first problem I ran into is that the voltage across the shunt is so small that you cannot really use a scaling circuit and get a meaningful voltage value. You would need to scale the 0.001 V to 0.0002 V and I don't think this makes sense. I was attempting to amplify the shunt voltage, but that results in amplification of the noise, and I cannot find anyone who can help me adjust the amplifiers offset. The only other route I can think of is to use a higher resistance shunt, but then the power dissipated at the shunt is very large. I don't think that is a good idea. I want to have a range up to 100 A. Is there any simple way to achieve this?
