temperature range, otherwise specifications are at T
otherwise noted.
Industrial Grade – 40 C to 85 C. V
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LT1614C is guaranteed to meet specified performance from
0 C to 70 C and is designed, characterized and expected to meet these
extended temperature limits, but is not tested at – 40 C and 85 C. The
LT1614I is guaranteed to meet the extended temperature limits.
