- dekhn 3y agoladyada made a board design that incorporates a class-D amplifier chip, it's open source: https://www.adafruit.com/product/1752 https://www.adafruit.com/product/1752 https://github.com/adafruit/Adafruit-MAX9744-Amplifier-PCB https://github.com/adafruit/Adafruit-MAX9744-Amplifier-PCB I'm not sure which is the hard part you're referring to- implementing the amplifier itself, or the board around it. I don't think an amateur would want to build their own class-D from raw components except for pedagogical purposes. (i've been pretty happy with the results, I used the board to drive a couple speakers and the amplifier is not the first thing I'd fix to improve the audio quality.
