Can an op amp amplify beyond its Vcc?

Question

This should be a simple question.

If i want to shift a wave that travels between +/- 5 Volts...would it be possible to simply shift the wave up by its Vcc value so the wave varies between 0 and 10V? I am trying to maintain resolution on a signal.

Answer 1

beyond Vcc the Op Amp stage is going to clip the waveshape and will not result in amplification

Answer 2

waves don't have Vcc, that is a term applied to the voltage supplied to a circuit.

Do you want to shift a signal by 5 volts, that is easy. just use an inverting opamp with a fixed current into the negative input together with the signal. But you will need an opamp running off of +12 and -2 at least.

Or do you want to shift the signal up by it's peak value? That is more complicated and involves a peak detector.

Answer 3

No.

Answer 4

It needs one more stage called buffer or emitter follower to fulfil what you need.
