Backside of Buffalo II DAC

If you own a Buffalo II DAC, you might have noticed that in the backside, there are a few ferrite beads:

  • L1-L5 are ferrite beads at the outputs of the local regulators into the DAC. TPA has been doing this for their designs. Take a look at the circuit diagram for the OPUS DAC.
  • L6-L8 are ferrite beads at the inputs of the LT1763 regulators. Removing these will disable these local regulators (so you can use your favorite regulator instead)
  • Ferrite beads are used for EMI noise suppression. This application note from Murata describe the properties of ferrite beads
