Absolute maximum ratings

Note:

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.

to use this device using externally applied voltage to V+ and V-.
