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 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 circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150˚C.
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

)/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.
