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 LT3467E/LT3467AE are guaranteed to meet performance

specifications from 0°C to 85°C, junction temperature. Specifications over

the –40°C to 85°C operating junction temperature range are assured by

design, characterization and correlation with statistical process controls.

The LT3467I/LT3467AI are guaranteed over the full –40°C to 125°C

operating junction temperature range.
