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.
