uPower Class D headphone Amp
 
Hi All.. my first post.. I note much of info here is for hi-end amps, with lots of grunt.

I designed a feed-forward noise blanking analog amp many years ago (for hearing protection, with weapons)

I now think it's time to uprate the amp side to Class D, most of the headphone amps here are way to heavy on power requirements.

I ran the original design on 3.6V, current draw was a few mA at peak levels.

Has anyone found a low voltage uPower class D chip in passing?
I'm still searching here, ideally not uBump package initially, as I need to prototype in house, along with much tweaking & optimising ;-)

Any info would be appreciated.

Steve
