I only want to amplify the average value of the waveform in post #4.......will the opamp be able to do this accurately ?
...its just that i worry about the effect of GBW product..................
OPA335 GBW = 2MHz so with a gain of 100, i'll have about 20kHz bandwidth, the amplifier isn't fast enough to even see the waveform.........................is this a problem?
....i thought the capacitors C1 and C2 in the schem in #4 post would filter the current sense resistor waveform, and result in the average vaue of the current sense resistor voltage being accurately amplified?.......................am i wrong in this?
