[AK4633]
Handling of Unused Pin
The unused I/O pins should be processed appropriately as below.
Classification
Analog
Pin Name
MIC/MICP, BEEP/MICN, MPI, AOUT,
SPP, SPN, VCOC
MCKI, SDTI
Setting
These pins should be open.
These pins should be connected to DVSS.
These pins should be connected to DVSS, or should
FCK, BICK (Note)
Digital
be pulled-down/pulled-up by about 100kΩ resister .
MCKO, SDTO
These pins should be open.
(Note) When the AK4633 is used by the slave mode (M/Sbit=“0”), these pins should be connected to DVSS. When the
AK4633 is used by the master mode (M/Sbit=“1”), these pins should be pulled-down or pulled-up by about 100kΩ
resistor.

Note 2. All voltages with respect to ground.
Note 3. AVSS, DVSS and SVSS must be connected to the same analog ground plane.
Note 4. In case that PCB wiring density is 100%. This power is the AK4633 internal dissipation that does not include
power of externally connected speaker.
Note 5. BEEP/MICN, MIC/MICP pins
Note 6. PDN, CSN, CCLK, CDTI, SDTI, FCK, BICK, MCKI pins
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
