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 LTC3524E is guaranteed to meet specifi cations from 0°C to
85°C. Specifi cations over the –40°C to 85°C operating temperature range
are assured by design, characterization, and statistical process controls.
