Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical characteristics.
Note 2:
Human body model, 1.5 k
in series with 100 pF.
Note 3:
Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150C. Output currents in excess of
±
30 mA over long term may adversely affect reliability.
Note 4:
The maximum power dissipation is a function of T

Note 5:
Typical Values represent the most likely parametric norm.
Note 6:
All limits are guaranteed by testing or statistical analysis.
Note 7:
Do not short circuit output to V+, when V+ is greater than 13V or reliability will be adversely affected.
Note 8:
Slew rate is the slower of the rising and falling slew rates.
