ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the full operating
temperature range of 0°C ≤ TA ≤ 70°C. VS = ±5V, Pin 5 open circuit unless otherwise noted.

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/2πVP.
Note 6: Settling time measurement techniques are shown in “Take the
Guesswork Out of Settling Time Measurements,” EDN, September 19,
1985. AV = –1, RL = 1k.
Note 7: NTSC (3.58MHz). For RL = 1k, Diff AV = 0.1%, Diff Ph = 0.06°.
Note 8: See Applications section for shutdown at elevated temperatures.
Do not operate the shutdown above TJ > 125°C.
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).
