Need some help interfacing a JRKerr controller that has a PWM output and a direction bit, to an amp that needs a +10/-10 referance voltage. I imagine you would need a couple AND gates, inverters and prob a push-pull circuit of some sort. I'm not concerned with the inbetween values, I just want it to go from 0 to +10/-10 depending on the direction bit. I was just wondering if anyone has any ideas. :?
