AK4649VN
24bit Stereo CODEC with MIC/SPK-AMP
GENERAL DESCRIPTION
The AK4649VN features a stereo CODEC with a built-in Microphone-Amplifier and Speaker-Amplifier.
Input circuits include a Microphone-Amplifier and an ALC (Automatic Level Control) circuit, and Output
circuits include a Speaker-Amplifier. These circuits are suitable for portable application with
recording/playback function. The AK4649VN is available in 32pin QFN(5x5mm 0.5mm pitch) utilizing less
board space than competitive offerings.

Note 2. All voltages are with respect to ground.
Note 3. VSS1, VSS2 and VSS3 must be connected to the same analog ground plane.
Note 4. MIN, LIN1, RIN1, LIN2 and RIN2 pins
Note 5. PDN, CSN, CCLK, CDTIO, SDTI, LRCK, BICK and MCKI pins
Note 6. In case that PCB wiring density is 200% over and surface wiring density is 50% over. This power is the
AK4649VN internal dissipation that does not include power dissipation of an 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 2. All voltages are with respect to ground.
Note 7. The power-up sequence between AVDD, DVDD and SVDD is not critical. The PDN pin must be “L” upon power
up, and should be changed to “H” after all power supplies are supplied to avoid an internal circuit error.
* When DVDD is powered ON and the PDN pin is “L”, AVDD or SVDD can be powered OFF.
However, when AVDD is powered OFF, the power supply current of DVDD at power-down
mode may be increased. When the AK4649VN is changed from power down state to power
ON, the PDN pin must be “H” after all power supplies are ON.
* AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
