Absolute maximum ratings
Absolute maximum ratings
Absolute maximum ratings are those values beyond which damage to the device may occur.
Functional operation under these condition is not implied.
Externally applied V+ and V- can have a maximum magnitude of +7 V, but their absolute
addition can not exceed 13 V.
Running on internal charge pump, intrinsic self limitation allows exceeding those values
without any damage.
