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/DMCLK, MIC/MICP/DMDAT, BEEP 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. VIN pin
Note 5. AK4636ECB: When PCB wiring density is more than 200% and superficial layer writing density is more than
50%. AK4636EN: When PCB wiring density is more than 100%.
This power is the AK4636 internal dissipation that does not include power of externally connected speakers.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
