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, RIN2/IN2−, LIN2/IN2+, LIN1/IN1−, RIN1/IN1+ pins
Note 6. PDN, CSN/CAD0, CCLK/SCL, CDTI/SDA, SDTI, LRCK, BICK, MCKI pins
WARNING: Operation at or beyond these limits may result in permanent damage to the device.

Handling of Unused Pin
Pull-up resistors at SDA and SCL pins should be connected to (DVDD+0.3)V or less voltage.
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.
