Absolute maximum ratings
Table 1.
1. All voltage values are measured with respect to the ground pin.
2. The magnitude of input signal must never exceed V
3. Device is protected in case of over temperature by a thermal shutdown active @ 150° C.
4. Exceeding the power derating curves during a long period, may provoke abnormal operation.
