Notes: 5. All voltages with respect to ground.
6. AVSS and DVSS 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: 5. All voltages with respect to ground.
7. The power up sequence between AVDD, DVDD and TVDD is not critical.
Do not turn off only the AK4626A under the condition that a surrounding device is powered on and the I2C bus
is in use.
WARNING: AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
