Note 3. All voltages with respect to ground.
Note 4. AVSS, DVSS and HVSS must be connected to the same analog ground plane.
Note 5. I2C, MIN, RIN2/IN2−, LIN2/IN2+, LIN1/IN1−, RIN1/IN1+ pins
Note 6. PDN, CSN/CAD0, CCLK/SCL, CDTI/SDA, 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 AK4642 internal dissipation that does not include
power of externally connected speaker and headphone.
Note 8. Speaker-Amp is not available.
Note 9. Speaker-Amp is available.
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. All voltages with respect to ground.
Note 10. The power-up sequence between AVDD, DVDD and HVDD is not critical. When the power supplies are
partially powered OFF, the AK4642 must be reset by bringing PDN pin “L” after these power supplies are
powered ON again.
Note 11. HVDD = 2.6 ∼ 3.6V when 8Ω dynamic speaker is connected to the AK4642.
