Note 1. All voltages with respect to ground.
Note 2. DVSS means DVSS1 and DVSS2.
Note 3. DVDD means DVDD1 and DVDD2.
Note 4. AVSS, DVSS, HVSS and TSVSS must be connected to the same analog ground plane.
Note 5. MIN, AIN, MDT/RIN, MPE/LIN, EXT/MIC+, INT/MIC
, AUXIN
, AUXIN+, BEEP/IN2 pins
Note 6. HDT pin
Note 7. XTI/MCKI, XTO/PLL0, SDATAOUT, SYNC, RESETN, PLL1, ADEXE pins

Note 1. All voltages with respect to ground.
Note 2. DVSS means DVSS1 and DVSS2.
Note 3. DVDD means DVDD1 and DVDD2.
Note 9. The power up sequence between AVDD, DVDD, HVDD and TSVDD is not critical. When the voltage difference
among AVDD, DVDD, HVDD and TSVDD is larger than 0.3V, the power supply current at power down mode
increases (Note 28). When the power supplies are partially powered OFF, the AK4650 must be reset by bringing
PDN pin “L” after these power supplies are powered ON again. DVDD1 and DVDD2 should be same voltage.
* AKEMD assumes no responsibility for the usage beyond the conditions in this datasheet.
