Note 1: Absolute Maximum Ratings are those values beyond which the life of
a device may be impaired.
Note 2: The LT1932E 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.
Consult LTC Marketing for parts specified with wider operating temperature
ranges.
