Note 3. All voltages are with respect to ground.
Note 10. The power-up sequence between AVDD, DVDD, TVDD and SVDD is not critical. The PDN pin must be “L”
upon power up, and should be changed to “H” after all power supplies are supplied to avoid an internal circuit
error.
* When SVDD is powered ON and the PDN pin is “L”, AVDD, DVDD or TVDD can be powered
ON/OFF. When TVDD is powered ON and the PDN pin is “L”, AVDD, DVDD or SVDD can be
powered ON/OFF. When the AK4953A is changed from power down state to power ON, the
PDN pin must be “H” after all power supplies are ON.
* AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
