Note 2. All voltages are with respect to ground. VSS1, VSS2 and VSS3 must be connected to the same
analog ground plane.
Note 3. LIN1, RIN1, LIN2, RIN2, LIN3 and RIN3/BEEP pins
Note 4. 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 5.This power is the AK4951A 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). When Pd =840mW and the θja is 42C/W, the junction
temperature does not exceed 125C. In this case, the AK4951A will not be damaged by its internal
power dissipation. Therefore, the AK4951A should be used in the condition of θja ≤ 42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.
