Notes:
1. All voltages with respect to ground.
2.AVSS, DVSS and PVSS 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.

Notes:
3. All voltages with respect to ground.
4. The power up sequence between AVDD, DVDD, PVDD and TVDD is not critical. To save leak current in power
down mode, AVDD, DVDD, PVDD become the same voltage as much as possible.
WARNING: AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
