Note 1: Absolute Maximum Ratings are those values beyond which the
life of a 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: There are two limitations on signal swing. Output swing is limited
by clipping or saturation in the output stage. Input swing is controlled by
an adjustable input limiting function. On VS = ±5V, the overload
characteristic is output limiting, but on
±8V the overload characteristic is
input limiting. VOMAX is measured with the null pins open circuit.
Note 4: Output amplitude is reduced by the input limiting function. The
input limiting function occurs when the null pins, 1 and 8, are tied together
and raised to a potential 0.3V or more above the negative supply.
Note 5: Slew rate is measured between
±1V on the output, with a ±0.3V
input step.
Note 6: Full-power bandwidth is calculated from the slew rate
measurement:
FPBW = SR/2
πVP.
Note 7: Settling time measurement techniques are shown in “Take the
Guesswork Out of Settling Time Measurements,” EDN, September 19,
1985.
Note 8: NTSC (3.58MHz).
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 part (S suffix).
