Note 2. All voltages with respect to ground. VSS1 ~ 3 must be connected to the same analog ground plane.
Note 3. In case that PCB wiring density is 100%.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

Note 4. The power up sequence between AVDD1, AVDD2 and TVDD is not critical. Each power supplies should be
powered up during the PDN pin = “L”. 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 AK4618 under the
condition that a surrounding device is powered on and the I2C bus is in use. AVDD1 and AVDD2 must be
connected with the same power supply.
WARNING: AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
