Note 1. All indicated voltages are with respect to ground.
Note 2. VSS1-6 must be connected to the same 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 3. The power supply sequence for AVDD and DVDD is not critical but all power supplies must be On before start
operating the AK7722.
Note 4. Do not turn off the power supply of the AK7722 with the power supply of the surrounding device turned on.
DVDD must not exceed the pull-up of SDA and SCL of I2C BUS. (The diode exists for DVDD in the SDA and
SCL pins.)
WARNING: AKM assumes no responsibility for the usage beyond the conditions in the datasheet.
