Note 5. The power up sequence between AVDD and DVDD is not critical. Each power supplies should be powered up
during the PDN pin = “L”. AVDD and DVDD must be the same voltage at the PDN pin = “H”. The PDN pin
should be “H” after all power supplies are powered up. All power supplies should be powered on, only a part
of these power supplies cannot be powered off. (Power off means power supplies equal to ground or power
supplies are floating.) Do not turn off only the AK4753 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.
