I am looking to amplify a DC signal that will range from 0 to 400mV by at around 5-10X and read it with my DAQ.
I currently have a TLV271 and a UA741CP that I tried to use in a non-inverting circuit. I can't get it work as I would like.
The signal is coming straight from an electric guitar. Will either of the op-amps I have work for me? If not which one should I buy. Also I have another DAQ that can take up to 15V input to read the signal that I can use it that makes things easier.
In my circuit Rf was 4.7K ohm and R2 was 1K ohm with supply being 5V and 0V ground.
