(1) Unless otherwise noted, the absolute maximum ratings are specified over operating conditions. Stresses beyond those listed under

Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only. Exposure to

absolute-maximum-rated conditions for extended periods may affect device reliability.

(2) The analog inputs have an internal clamping circuit that clamps the voltage to a diode drop above V

DDA

or below V

. The continuous

clamp current per pin is ±2 mA.
