(Note 8)
Note 4. All voltages with respect to ground.
Note 5. VSS1, VSS2, and VSS3 must be connected to the same analog ground plane.
Note 6. RIN4/IN4
, LIN4/IN4+, MIN/LIN3, RIN3, RIN2/IN2
, LIN2/IN2+, LIN1/IN1
, and RIN1/IN1+ pins
Note 7. PDN, SCL, SDA, SDTI, LRCK, BICK, MCKI, and CAD0 pins
Pull-up resistors at SDA and SCL pins should be connected to (TVDD+0.3) V or less voltage.
Note 8. In case that PCB wriring density is 300% or more. This power is the AK4648 internal dissipation that does not
include power of externally connected speaker and headphone.
Note 9. Stereo SPK Mode is not available.
Note 10. In case of Stereo SPK Mode, Ta (max) is 70
°
C and HVDD voltage range is from 2.6V to 4.6V.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
