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

of a device may be impaired.

Note 2: The LTC3466-1E is guaranteed to meet specified performance

from 0

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

are assured by design, characterization and correlation with statistical

process controls.

Note 3: Current flows out of the pin.

Note 4: Guaranteed by design and test correlation, not production tested.
