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. LT1931I/LT1931AI are
guaranteed over the –40 ° C to 85 ° C temperature range.
Note 3: Current limit guaranteed by design and/or correlation to static test.
