BAT
denotes specifications which apply over the full operating
Note 3: Does not include tolerance of current sense resistor or current
programming resistor.
Note 4: The LTC4007E is 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.
