Power Supplies:
Input Current, Any Pin Except Supplies
Analog Input Voltage
Digital Input Voltage
Ambient Temperature (powered applied)
Storage Temperature
Note 1. All voltages with respect to ground.
Note 2. AVSS, DVSS, PVSS and HVSS must be connected to the same analog ground plane.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.

Parameter
Power Supplies
Note 1. All voltages with respect to ground.
Note 3. The power up sequence between AVDD, DVDD, HVDD and PVDD is not critical.
* AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
MS0273-E-00
(Note 3)
When the voltage difference among DVDD, PVDD and AVDD is larger than 0.3V, the power supply current at
power down mode increases (see Note 19).
When the power supplies are partially powered OFF, the AK4640 must be reset by bringing PDN pin “L” after
these power supplies are powered ON again.
Normal operation is not guaranteed at these extremes.
