Short-circuits can cause excessive heating and destructive dissipation. 2. Rth are typical values. 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. Start-up 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-. Figure 2.
