Analog Supply
(3.0V)
- VSS of the AK4556 should be distributed separately from the ground external digital devices.
- Do not allow digital input pins to float.
- When LOUT/ROUT drives some capacitive load, a 220Ω resistor should be added in series between LOUT/ROUT
and capacitive load. In this case, LOUT/ROUT pins can drive capacitor of 400pF.
