Note 1. All voltages with respect to ground.
Note 2. AVSS means AVSS1 and AVSS2. DVSS means DVSS1 and DVSS2.
Note 3. AVDD means AVDD1 and AVDD2.
Note 4. DVDD means DVDD1 and DVDD2.
Note 5. AVSS, DVSS and HVSS must be connected to the same analog ground plane.
Note 6. MIN, AIN, MDT/RIN, MPE/LIN, EXT/MIC+, INT/MIC−, AUXIN−, AUXIN+, BEEP pins
Note 7. HDT pin
Note 8. XTI/MCKI, XTO/PLL0, SDATAOUT, SYNC, RESETN, PLL1 pins
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. DVDD1 and DVDD2 should be same voltage.
Note 2. AVSS means AVSS1 and AVSS2. DVSS means DVSS1 and DVSS2.
Note 3. AVDD means AVDD1 and AVDD2.
Note 4. DVDD means DVDD1 and DVDD2.
Note 9. The power up sequence between AVDD, DVDD and HVDD is not critical. When the voltage difference among
AVDD, DVDD and HVDD is larger than 0.3V, the power supply current at power down mode increases (see Note
28). When the power supplies are partially powered OFF, the AK4651 must be reset by bringing PDN pin “L”
after these power supplies are powered ON again. DVDD1 and DVDD2 should be same voltage.
