Note 2. All voltages are with respect to ground.
Note 6.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 7. The minimum value is higher voltage between DVDD-0.2 and 1.6V.
* When SVDD is powered ON and the PDN pin is “L”, AVDD, DVDD and TVDD can be
powered ON/OFF. When TVDD is powered ON and the PDN pin is “L”, AVDD, DVDD and
SVDD can be powered ON/OFF. The PDN pin must be set to “H” after all power supplies
are ON, when the AK4951A is powered-up from power-down state.
* AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
