I'm using OPA1632 to amplify the signal coming from a microphone. As I'm only testing the circuit right now, the amplifier is configured with a gain of 2. I'm using +-12 supplies.
My problem is that the amplifier is clipping part o the signal at 1 V output.
Using a single ended input of 1,25 V at the non inverted input, I got this output (Vout+ in yellow, Vout- in blue):
My circuit is (R1 and R2 are 100k on the board):
I already used the same circuit in another board, with the difference that Vocm was not tied to GND, but to a CM voltage, and had no problem.
I would appreciate any help.
