After quite a bit of hard work, we have a new board for the audio ADC converter, made of 4 layers: analog signals at the top, digital signals at the bottom, ground and power in the middle. No shared vias, no duplication of power inputs, no nasty capacitors on the audio input path. And thanks to this redesign, we managed to make the board a lot smaller: 86 × 38 mm.

Next step: audio DAC board.
