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.
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 and HVDD is not critical. When the power supplies are partially
powered OFF, the AK4647 must be reset by bringing PDN pin “L” after these power supplies are powered ON
again.
When AVDD or HVDD is powered OFF, the power supply current of DVDD at power-down mode may be
increased. DVDD should not be powered OFF while AVDD or HVDD is powered ON.
* AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
