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.
It is recommended that DVDD and PVDD are the same voltage as AVDD in order to reduce the current at power
down mode.
* AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
