Note 7. 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.
Note 8. The minimum value is higher voltage between DVDD-0.2V and 1.6V.
* When TVDD is powered ON and the PDN pin is “L”, AVDD, DVDD or SVDD can be powered
ON/OFF. The PDN pin must be set to “H” after all power supplies are ON when the AK4695 is
powered-up from power-down state.
* AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
