Consult LTC Marketing for parts specified with wider operating temperature ranges.
Note 3: The LT3462E 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.
