Note 4. All voltages with respect to ground.
Note 7. The power up sequence between AVDD, DVDD and TVDD is not critical. Do not turn off only the AK4629 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.
