Maximum Power Dissipation (Note 5)

Note 1. All voltages with respect to ground.

Note 2. AVSS, DVSS, HVSS and PVSS must be connected to the same analog plane.

Note 3. LIN and RIN pins. The maximum value is low value either “AVDD+0.3V” or “4.0V”.

Note 4. MCLK, BICK, LRCK, SDATA, CAD0/CSN, SCL/CCLK, SDA/CDTI, I2C and PDN pins. The maximum value

is low value either “TVDD+0.3V” or “4.0V”.

Pull-up resistors at SDA and SCL pins should be connected to (TVDD+0.3)V or less voltage.

Note 5. In case that PCB wiring density is 100%. This power is the AK4342 internal dissipation that does not include

power of externally connected headphone.

WARNING: Operation at or beyond these limits may result in permanent damage to the device.

Normal operation is not guaranteed at these extremes.

Note 1. All voltages with respect to ground.

Note 6. Power up sequence among AVDD, DVDD, HVDD, PVDD and TVDD is not critical. But PDN pin

must keep “L” until all power supply pins are applied. After that, PDN pin should be set to “H”.

Each power supply cannot be partially powered OFF.
