Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended 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 kΩ 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 150˚C. 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
J(max)
,
θ
JA
and T
A
. The maximum allowable power dissipation at any ambient temperature is P
D
= (T
J(max)
− T
A
)/θ
JA
. All numbers apply for packages soldered directly into a PC board.
Note 5:
Typical Values represent the most likely parametric norm.
Note 6:
All limits are guaranteed by testing or statistical analysis.

Note 8:
Do not short circuit output to V

, when V

is greater than 13V or reliability will be adversely affected.
Note 9:
V

Note 11:
Guaranteed limits are dictated by tester limits and not device performance. Actual performance is reflected in the typical value.
