Default UCD as power conditioner

Ok, this is probably a dumb idea.

But given the output impedance of the UCD700 amps, could one be used as a AC 110 volt power conditioner?

I suppose there's enough of the RF carrier riding on the output to make that a really bad idea.

It's not a bad idea, class D is routinely employed for sine wave synthesys in high quality DC to AC inverters. However, note that audio class D amplifiers are optimized to achieve wide bandwidth up to 20Khz rather than low carrier components on the output, so they may benefit from some modifications. A 500Hz bandwidth would suffice for a power conditioner.

I'm not sure the module would stand continous operation with a sine-wave input, but who knows?
EDIT: Meaning you would probably only be able to draw between 1/8 and 1/3 power contionously.
