Note 3. All voltages are with respect to ground.
Note 4. AVSS, DVSS and SVSS must be connected to the same analog ground plane.
Note 5.MIN, RIN2/IN2−, LIN2/IN2+, LIN1/IN1−, RIN1/IN1+ pins
Note 6. PDN, CSN, CCLK, CDTIO, SDTI, LRCK, BICK, MCKI pins
Pull-up resistors at SDA and SCL pins should be connected to DVDD or less voltage.
Note 7. In case that PCB wiring density is 100%. This power is the AK4646 internal dissipation that does not include
power of externally connected speaker.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

Note 8. The power-up sequence between AVDD, DVDD and SVDD is not critical. When AVDD or SVDD is powered
OFF, the power supply current of DVDD at power-down mode may be increased. When the power supplies are
partially powered OFF, the AK4646 must be reset by bringing PDN pin “L” after these power supplies are
powered ON again.
Note 9. SVDD = 2.2
∼
3.6V when 8Ω dynamic speaker is connected to the AK4646.
* AKEMD assumes no responsibility for the usage beyond the conditions in this datasheet.
