Note 1. All voltages with respect to ground. VSS21, VSS2 and VSS3 must be connected to the same analog ground plane.
Note 2.When PCB wiring density is 100%. This power is the AK4635 internal dissipation that does not include power of
Note 3. LIN/MICN, MIC/MICP,VIN pins
Note 4. PDN, I2C, CSN/SDA, CCLK/SCL, CDTIO, SDTI, FCK, BICK, MCKI pins
WARNING: Operation at or beyond these limits may result in permanent damage to the device.

Parameter
Power Supplies
Note 1. All voltages with respect to ground.
Note 5. The power up sequence between AVDD, DVDD and SVDD is not critical. It is not permitted to power DVDD off
Note 6. Video Amp is used (PMV bit = “1”). When Video Amp is not used (PMV bit = “0”), Min. spec of AVDD is 2.2V.
* AKEMD assumes no responsibility for the usage beyond the conditions in this datasheet.

Handling of Unused Pin
(Note
externally connected speaker.
when AVDD or SVDD is powered up. When only AVDD or SVDD is powered OFF, the AK4635 must be reset
by bringing the PDN pin “L” after theses power supplies are powered ON again. The power supply current of
DVDD at power-down mode may be increased. DVDD should not be powered OFF while AVDD or SVDD is
powered ON.
Pull-up resistors at SDA and SCL pins should be connected to (DVDD+0.3)V or less voltage.

Normal operation is not guaranteed at these extremes.
