Note 3. All voltages with respect to ground.
Note 4. AVSS, DVSS and HVSS must be connected to the same analog ground plane.
Note 5. I2C, MIN/LIN3, RIN3, RIN2/IN2−, LIN2/IN2+, LIN1/IN1−, RIN1/IN1+ pins
Note 6. PDN, CSN/CAD0, CCLK/SCL, CDTI/SDA, SDTI, LRCK, BICK, MCKI pins
Pull-up resistors at SDA and SCL pins should be connected to (DVDD+0.3)V or less voltage.
Note 7. In case that the exposed pad is connected to the ground and PCB wiring density is 100%. If the exposed pad is
open, Pd1=400mW(max: Speaker-Amp is not available.) and Pd2=550mW(max: Speaker-Amp is available at
HVDD=2.6∼3.6V.). This power is the AK4343 internal dissipation that does not include power of externally
connected speaker and headphone.
Note 8. Speaker-Amp is available at HVDD=2.6∼3.6V.
Note 9. Speaker-Amp is available at HVDD=2.6∼5.25V.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
