[AK4634]  
Handling of Unused Pin  
The unused I/O pins should be processed appropriately as below.  
Classification  
Analog  
Pin Name  
Setting  
These pins should be open  
MIC/MICP, LIN/MICN, MPI, AOUT,  
SPP, SPN, VCOC  
MCKI, SDTI  
These pins should be connected to VSS2  
When I2C pin = “H”, These pins should be  
connected to VSS2.  
Digital  
CDTIO  
MCKO, SDTO  
These pins should be open.

Maximum Power Dissipation (Note 4)  
Note 1. All voltages with respect to ground. VSS21, VSS2 and VSS3 must be connected to the same analog ground plane.  
Note 2. LIN/MICN, MIC/MICP pins  
Note 3. PDN, I2C, CSN/SDA, CCLK/SCL, CDTIO, SDTI, FCK, BICK, MCKI pins  
Pull-up resistors at SDA and SCL pins should be connected to (DVDD+0.3)V or less voltage.  
Note 4.When PCB wiring density is 100%. This power is the AK4634 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 1. All voltages with respect to ground.  
Note 5. The power up sequence between AVDD, DVDD and SVDD is not critical.  
Do not power DVDD off when AVDD or SVDD is powered up.  
When only AVDD or SVDD is powered OFF, the AK4634 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.  
* AKEMD assumes no responsibility for the usage beyond the conditions in this datasheet.
