Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: The LT3461E/LT3461AE is guaranteed to meet 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.
