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 LT3483E/LT3483AE are guaranteed to meet 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. The LT3483I/LT3483AI are guaranteed to meet

specifications over the –40°C to 125°C operating temperature range.

Note 3: Current flows out of the pin.
