Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Conditions indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The
guaranteed specifications apply only for the test conditions listed.
Note 2:
Applies to both single-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed
junction temperature of 110˚C. Output currents in excess of
±
30 mA over long term may adversely affect reliability.
Note 3:
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
.
Note 4:
Human body model, 1.5 kΩ in series with 100 pF.
Note 5:
Typical values represent the most likely parametric norm.
Note 6:
All limits are guaranteed at room temperature (standard type face) or at operating temperature extremes (bold face type).
