250hz sine wave drive with h-bridge amplifier

Not sure how to set up a sinewave drive from a pic to a h-bridge. Any advice? Specifically the PIC code.
thanks!!

sinewave? Usually H-bridge architectures are driven with squarewaves (logic like a PIC)

Why do you need to drive the bridge with a sinewave?

That is what i thought, but the that is what the specs call for. Here is a link to the specs.

Maybe H-Bridge is not the best solution?

Are you after a sinewave output


What you need to do is use the PIC to generate a PWM-based image of a Sinewave

NO, H-bridge is ok. I think they are talking about what is needed to drive this unit. So you can create an H bridge driver with t he sinewave bursts on the output. It is sinewave outputs as the "driver" of this unit. Of course, the input to the bridge will be the usual squarewaves. Those specs are not trying to tell you how to make the driver just what the driver needs to output to properly interface with the unit.

ahh, that makes sense, i was pretty confused for a bit
thanks!!
