The
temperature range.
Note 1: The LTC1659CMS8 is designed, characterized and expected to
meet industrial temperature limits, but is not tested at – 40 C and 85 C.
Consult factory for guaranteed I-grade MSOP parts. However, these parts
are guaranteed for commercial temperature limits of 0 C to 70 C.
Note 2: Nonlinearity is defined from code 20 to code 4095 (full scale). See
Applications Information.
