Hey, seeing as how there are 2 more people in chat now, maybe someone knows the answer to my question:
I'm using an op-amp here, as a non-inverting amplifier, but the circuits hooked up to input and output pins don't share a common ground. (I have a microphone as the input). How should I wire this?
(I'm trying to use it as a non-inverting amplifier. But it's being fed into a microcontroller after this for processing, so inverting is ok if necessary.)
