ELECTRICAL CHARACTERISTICS
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
The LT1931E/LT1931AE are guaranteed to meet performance
specifications from 0
°
C to 70
°
C. Specifications over the –40
°
C to 85
°
C
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
Note 3:
Current limit guaranteed by design and/or correlation to static test.
Consult factory for parts specified with wider operating temperature ranges.
