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 ±3V

input step.

Note 5: Full-power bandwidth is calculated from the slew rate

measurement:

FPBW = SR/2

Note 6: Settling time measurement techniques are shown in “Take the

Guesswork Out of Settling Time Measurements,” EDN, September 19,

Note 8: See Applications section for shutdown at elevated temperatures.

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).
