Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTC1503C 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 are not tested at – 40 C and 85 C. The
LTC1503I is guaranteed to meet the extended temperature limits.
