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