† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. The magnitude of the input voltage must never exceed the magnitude of the supply voltage.

2. Excessive input current will flow if a differential input voltage in excess of approximately 0.6 V is applied between the inputs, unless

some limiting resistance is used.

3. The output may be shorted to ground or either power supply. Temperature and/or supply voltages must be limited to ensure the

maximum dissipation rating is not exceeded.

4. Maximum power dissipation is a function of TJ(max), qJA, and TA. The maximum allowable power dissipation at any allowable

ambient temperature is PD = (TJ(max) − TA)/qJA. Operating at the absolute maximum TJ of 150°C can impact reliability.

5. The package thermal impedance is calculated in accordance with JESD 51-7.
