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 LTC3426 is guaranteed to meet performance specifications

from 0

°C to 85°C. Specifications over the –40°C to 85°C operating

temperature are assured by design, characterization and correlation with

statistical process controls.

Note 3: This IC includes overtemperature protection that is intended to

protect the device during momentary overload conditions. Junction

temperature will exceed 125

°C when overtemperature protection is active.

Continuous operation above the specified maximum operating junction

temperature may impair device reliability.

Consult LTC Marketing for parts specified with wider operating temperature ranges.
