Hello all, I'm new to electrical engineering, and I'm working on a project that requires a bit more than I'm familiar with. What I'm asking for help on boils down to this: I have a circuit that outputs a low power sine wave (frequency 25-40kHz) with an amplitude +/- 5V at a few watts. I want to amplify this sine wave signal to be at 110V RMS and 50W, or somewhere about there, it's flexible. I'm looking for some sort of IC or simple circuit that will allow me to amplify my input signal, and I was hoping for suggestions from the community. As a side note, would it be possible to do the same sort of amplification for a +/- 5V square wave rather than a sine wave? Is there some system that would do both? Thanks very much, an feel free to include as much information as you'd like, I'm hoping to learn something!
