I have linked to a dozen op-amps in a previous post. Please point me out one of them if you have the time. I need a robust one.

The 0V is important as the positive voltage will turn the motor in one direction and the negative in the other so at 0V it should stand still. But I could filter out a "dead zone" from the drive settings if necessary.
