† 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 in the recommended operating conditions section of this

specification is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. All voltage values, unless otherwise noted, are with respect to the midpoint between VCC+ and VCC−.

2. Differential input voltages are at IN+ with respect to IN−.

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

±15 V, whichever is less.

4. The output may be shorted to ground or to either power supply.

5. Maximum power dissipation is a function of TJ(max),

θ

JA, and TA. The maximum allowable power dissipation at any allowable

ambient temperature is PD = (TJ(max) − TA)/

θ

JA. Operating at the absolute maximum TJ of 150°C can affect reliability.

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