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.
Normal operation is not guaranteed at these extremes.

Note 1. All voltages with respect to ground.
Note 3. The power up sequence between AVDD, DVDD, HVDD and PVDD is not critical.
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.
* AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
