Note 3. All voltages are with respect to ground.
AVSSA, AVSSB, RVSS and SWVSS must be connected to the same analog ground plane.
RVDD/PVDDA/PVDDB and PVEEA/PVEEB must be connected to the same analog power
supplies each.
Note 4. Except RVDD, PVDDA, PVDDB, SWVDD, SWINA, SWINB, AUXA and AUXB pins
Note 5. SWINA, SWINB, AUXA and AUXB pins
Note 6. PINA, NINA, PINB and NINB pins
Note 7. The maximum value of VINA1 is (RVDD+0.3)V or 7.0V, whichever is lower.
Note 8. SWINA, SWINB, AUXA and AUXB pins at ON state
Note 9. The maximum value of VINA2, VINA3 and VIND is (SWVDD+0.3)V or 4.0V, whichever is lower.
Note 10. SWINA, SWINB, AUXA and AUXB pins at OFF state
Note 11. RSTN, SEL, MUTEN pins
Note 12.This value is the internal loss of the AK4205, excluding the consumption of external dumping
resistance and headphone. The maximum allowable junction temperature of the AK4205 is 125
C. The θja (Junction to Ambient) in JESD51-9(2p2s) is 39.6 C/W, and the internal
temperature rise is 0.5W × 39.6 = 19.8 C.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
