Note 1. All voltages with respect to ground.
Note 2. AVSS, DVSS and SVSS must be connected to the same analog ground plane.
Note 3. MIC, AIN, BEEP, MIN pins
Note 4. VIN pin
Note 5. In case that PCB wiring density is 100%. This power is the AK4632 internal dissipation that does not include
power of externally connected speaker.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
