Parameter Symbol Comments Value

Power supply voltage VDDD, VDDA -0.5 to 4.6V Note: Stresses beyond those listed

under “Absolute Maximum

Ratings” may cause permanent

damage to the device. These are

stress ratings only and functional

operation of the device at these or

any other conditions beyond those

indicated in the operational

sections of this specification is not

implied. Exposure to absolute

maximum rating conditions for

extended periods may affect device

reliability.
