Notes:
- LRCK = fs, BICK = 64fs.
- When AOUT drives some capacitive load, some resistor should be added in series between AOUT and
capacitive load.
- The capacitor of low ESR should be used to the capacitor (1). When it uses the capacitor with the polarity, the
positive pole of the capacitor should be connected to CP pin and VSS2 pin.
- All input pins except for the P/S pin should not be left floating.
