LT3491
ELECTRICAL CHARACTERISTICS
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 LT3491E is guaranteed to meet performance specifications
from 0 ° C to 85 ° C. Specifications over the –40 ° C to 85 ° C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
