I am looking for a low-performance unity gain instrumentation
amplifier to replace an "opamp & 4ea 1% resistors" circuit.
It doesn't have to be very good - it ends up feeding an
8-bit ADC - and it doesn't have to be very fast - the signal
is 60 Hz 3.5 VAC with <0.2V of common mode to be rejected.
What is important is minimum board space (I have to fit a lot
of them into a small space) and a cost that is no more than
three or four times what the opamp and four 1% resistors costs.
Does anyone have a favorite part that fits the above description?
