Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 2:
The LT3750E is guaranteed to meet performance specifications may cause permanent damage to the device. Exposure to any Absolute from 0°C to 70°C. Specifications over the –40°C to 85°C operating Maximum Rating condition for extended periods may affect device temperature range are assured by design, characterization and correlation reliability and lifetime. with statistical process controls.
