Note 4. All voltages are with respect to ground. VSS1, VSS2 and VSS3 must be connected to the same analog
ground plane.
Note 5. LIN1, RIN1, LIN2, RIN2, LIN3 and RIN3/BEEP pins
Note 6. PDN, CCLK/SCL, CSN/SDA, CDTIO/CAD0, SDTI, LRCK, BICK and MCKI pins
Pull-up resistors at the SDA and SCL pins must be connected to a voltage in the range from TVDD or
more to 6V or less.
Note 7. This power is the AK4951 internal dissipation that does not include power dissipation of externally
connected speakers. The maximum junction temperature is 125C and θja (Junction to Ambient) is
42C/W at JESD51-9 (2p2s) for the AK4951EN and 80C/W at JESD51-9 (2p2s) for the AK4951EG.
When Pd =840mW and the θja is 42C/W for the AK4951EN, the junction temperature does not
exceed 125C. When Pd =340mW and the θja is 80C/W for the AK4951EG, the junction temperature
does not exceed 125C. In this case, the AK4951 will not be damaged by its internal power dissipation.
Therefore, the AK4951EN should be used in the condition of θja ≤ 42C/W, and the AK4951EG
should be used in the condition of θja ≤ 80C/W.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
