Going for 4 layers

Following the advice of another mentor, I have decided to redesign my audio ADC module as a 4-layer board. This will give me the right impedance between power and ground, by putting them on two separate planes. The board will now be laid in the following fashion:

  • Top: Analog
  • Middle-Top: Power
  • Middle-Bottom: Ground
  • Bottom: Digital
