Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: Based on long term current density limitations.

Note 3: The LTC3200E/LTC3200E-5 are guaranteed to meet performance

specifications from 0

°C to 70°C. Specifications over the –40°C to 85°C

operating temperature range are assured by design, characterization and

correlation with statistical process controls.
