Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Specification is guaranteed by design and not 100% tested in
production.
Note 3: Measured from point at which V NEG crosses –5V to point at which
C2 – starts switching.
Note 4: The LTC3450E 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.
