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.

Startup voltage sequence (VCC, then V+, then V-) is critical, therefore it is not recommended

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