3498f

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 LT3498 is guaranteed to meet performance specifications

from 0°C to 85°C. Specifications over the –40°C to 85°C junction

operating temperature range are assured by design, characterization and

correlation with statistical process controls.
