[AK4633]
â Handling of Unused Pin
The unused I/O pins must be processed appropriately as below.
Classification
Pin Name
Setting
Analog
MIC/MICP, BEEP/MICN, MPI, AOUT,
SPP, SPN, VCOC
These pins must be open.
MCKI, SDTI
These pins must be connected to DVSS.
Digital
FCK, BICK (Note)
These pins must be connected to DVSS, or be
pulled-down/pulled-up by about 100kï resister .
MCKO, SDTO
These pins should be open.
(Note) When the AK4633 is used by the slave mode (M/Sbit=â0â), these pins must be connected to DVSS. When the
AK4633 is used by the master mode (M/Sbit=â1â), these pins should be pulled-down or pulled-up by about 100kï
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.
