Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

ELECTRICAL CHARACTERISTICS The ● denotes specifications which apply over the full operating temperature

range, otherwise specifications are at TA = 25°C. V+ = 10V, V– = 0V, LTC1043M operates from –55°C ≤ TA ≤ 125°C; LTC1043C operates from

–40°C ≤ TA ≤ 85°C, unless otherwise noted.

Note 2: OFF leakage current is guaranteed but not tested at 25°C.
