Default I2S Amp?

Hello folks,


Im interested in fully digital amps like:
TAS5706 simple full digital stereo amplifier - diyAudio


It would be nice to use a beaglebone and feed some amp boards.


I couldnt find much for fully digital amplifiers except some USB variants I have no use for.
Im especially looking for designs that make use of the PWM out capabilitys of the chips like the TAS5706B, so you get the full 2.1 with the processing per chip.
The datasheet looks quite nice but it seems to be trapped in comercial products.


Are there any projects outside I simply overlooked?
Unfortunately I just can assamble PCBs but got no clue about designing one.


Thank you very much and have an nice day.

There are actually a couple of them out there, but keep in mind that they basically just have a DAC onboard which converts to analog.

So just getting a separate DAC yourself is doing the same thing
