Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: See Test Circuit.
Note 3: Does not include tolerance of current sense resistor or current
programming resistor.
Note 4: The LTC4007E-1 is guaranteed to meet performance 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.
