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.

TJMAX = 125°C, θJA = 256°C/W IN FREE AIR

θJA = 120°C ON BOARD OVER GROUND PLANE
