Absolute Maximum Ratings*
*Comments
Logic supply voltage, Vcc
Supply voltage, AVDD
-0.5V to 5V
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
These are stress ratings only. Functional operation of this
device at these or under any other conditions above those
indicated in the operational sections of this specification are
not implied and exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
