ELECTRICAL CHARACTERISTICS
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
The LTC4440 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.
Note 3:
T
J
is calculated from the ambient temperature T
A
and power
dissipation PD according to the following formula:
T
J
= T

C/W)
Note 4:
Failure to solder the exposed back side of the MS8E package to
the PC board will result in a thermal resistance much higher than 40
°
C/W.
