Note 3. All voltages with respect to ground.
Note 4. AVSS and HVSS must be connected to the same analog ground plane.
Note 5. I2C, RIN4/IN4

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 (TVDD+0.3)V or less voltage.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

Note 3. All voltages with respect to ground.
Note 7. The power-up sequence between AVDD, DVDD, TVDD and HVDD is not critical. PDN pin should be held to
“L” upon power-up. PDN pin should be set to “H” after all power supplies are powered-up.
The AK4645 should be operated by the recommended power-up/down sequence shown in “System Design
(Grounding and Power Supply Decoupling)” to avoid the pop noise at line output and headphone output.
When one of power supplies is partially powered OFF, the power supply current at power-down mode may be
increased. All the power supplies should be powered OFF when the power supply is powered OFF.
* AKEMD assumes no responsibility for the usage beyond the conditions in this datasheet.
