Note 5. All voltages with respect to ground. VSS1, VSS2, VSS3 and VSS4 must be connected to the same analog ground
plane. AVDD1 and AVDD2 must be the same voltage.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

Note 6. The power up sequence between AVDD1, AVDD2, DVDD, TVDD1 and TVDD2 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
AK4614 under the condition that a surrounding device is powered on and the I2C bus is in use.
WARNING: AKEMD assumes no responsibility for the usage beyond the conditions in this datasheet.
