Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Operating Ratings indicate conditions for which the device is functional, but do not
guarantee specific performance limits. For guaranteed specifications and test
conditions, see the Electrical Characteristics. The guaranteed specifications apply
only for the test conditions listed. Some performance characteristics may degrade
when the device is not operated under the listed test conditions.
The maximum power dissipation msut be derated at elevated temperatures and is
dictated by Tjmax (maximum junction temperature), ThetaJA (package junction to
ambient thermal resistance), and TA (ambient temperature). The maximum allowable
power dissipation at any temperature is Pdmax = (Tjmax - TA)/ThetaJA or the number
given in the Absolute Maximum Ratings, whichever is lower.
May exceed input supply voltage.
When used in dual-supply systems where the output terminal sees loads returned to a
negative supply, the output voltage should be diode-clamped to ground.
