Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: This parameter is guaranteed to meet specified performance
through design and characterization. It has not been tested.
Note 3: The LT1671CS8 and LT1671CMS8 are guaranteed to meet
specified performance from 0 C to 70 C and are designed, characterized
and expected to meet these extended temperature limits, but are not tested
at – 40 C and 85 C. The LT1671IS8 is guaranteed to meet the extended
temperature limits.
Note 4: Input offset voltage (V
voltages measured by forcing first one output, then the other to 1.4V.
Note 5: Input bias current (I
currents.
Note 6: Input voltage range is guaranteed in part by CMRR testing and in
part by design and characterization.
