Note 4. All voltages are with respect to ground.
Note 8. 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 9. 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 AK4951EN is powered-up from power-down state.
