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 cannot exceed 13 V.

Note 1: V+ and V- can have maximum magnitude of 7V, but their absolute difference cannot exceed 13V.
