Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: The LT3755E and LT3755E-1 are guaranteed to meet performance

specifications from 0°C to 125°C junction temperature. Specifications over

the –40°C to 125°C operating junction temperature range are assured by

design, characterization and correlation with statistical process controls. The

LT3755I and LT3755I-1 are guaranteed to meet performance specifications

over the –40°C to 125°C operating junction temperature range.
