Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.

2. V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 13V.
