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-.
