Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: A heat sink is required to keep the junction temperature below
absolute maximum when the output is shorted.
Note 3: Exceeding the input common mode range may cause the output to
invert.
Note 4: Slew rate is measured between 1V on the output, with a 1.5V
input step.
Note 5: Full-power bandwidth is calculated from the slew rate
measurement:

Note 8: See Applications section for shutdown at elevated temperatures.
Do not operate the shutdown above T
Note 9: AC parameters are 100% tested on the ceramic and plastic DIP
packaged parts (J and N suffix) and are sample tested on every lot of the
SO packaged parts (S suffix).
