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 LT3467E/LT3467AE are guaranteed to meet performance
specifications from 0°C to 85°C. Specifications over the –40°C to 85°C
