Consult LTC Marketing for parts specified with wider operating temperature ranges.
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
Note 3: Failure to solder the exposed backside of the package to the PC
board ground plane will result in a thermal resistance much higher than
60 C/W.
