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 reli-
ability and lifetime.

ELECTRICAL CHARACTERISTICS
Note 2: The LT3482E is guaranteed to meet specifi ed performance from
0°C to 85°C. Specifi cations over the –40°C to 85°C operating temperature
range are assured by design, characterization and correlation with statisti-
cal process controls. The LT3482I is guaranteed to meet performance
specifi cations over the –40°C to 125°C operating temperature range.
