ELECTRICAL CHARACTERISTICS
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LT3465E/LT3465AE 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.
