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 operation at elevated ambient temperature can result in exceeding the maximum
allowed junction temperature at 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

θ
and T
. The maximum allowable power dissipation at any ambient temperature is P

Note 5:
Typical Values represent the most likely parametric norm.

Note 8:
Do not short circuit output to V
