Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: The LT3460E 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.
