Note 3. All voltages are with respect to ground.
Note 4. VSS1, VSS2, VSS3 and VSS4 must be connected to the same analog ground plane.
Note 5. LIN1, RIN1, LIN2, RIN2, LIN3, RIN3 pins
Note 6. PDN, CSN, CCLK, CDTIO, SDTI, LRCK, BICK and MCKI pins
Pull-up resistors at SDA and SCL pins should be connected to (TVDD+0.3)V or less voltage.
Note 7. In case that PCB wiring density is 100% over. This power is the AK4953A internal dissipation that does not
include power dissipation of externally connected speakers.
Note 8. The Speaker Amplifier is not available.
Note 9. The Speaker Amplifier is available.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
