OObbssoolleettee PPrroodduucctt((ss)) -- OObsolete P Note:

Absolute maximum ratings are those values beyond which damage to the device may occur.

Functional operation under these condition is not implied. V+ and V- can have a maximum

magnitude of +7V, but their absolute addition can not exceed 13 V.
