Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: The LT1937E is guaranteed to meet 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.
