I am working on an undergraduate project and I am inexperienced in electronics. I have a DC output from an differential amplifier using an op-amp. For simplification purposes lets say that the output from the op-amp varies between -3V to 3V. I would like to shift the voltage so that from -3V to 3V, I get something like 3V to 9V which I could then use to input into a power amplifier to run a DC motor.
Any guidance is greatly appreciated.
