- I am interested in a power amplifier that could drive a DC motor/actuator.
- I am using the actuator in a slow-response feedback loop. The power amplifier
- should interface an OP-AMP, that produces the error signal, and the
- actuator that demands up to 3 Amps for input voltages up to 20 volts.
- Therefore, I need a push-pull 60 W DC power amplifier. I have been able
- to find couple of power OP-AMPs that seem to to able to do the job. But,
- they are expensive - price is around $100.
- Thanks for any suggestion.
