TYPICAL PERFOR A CE CHARACTERISTICS

Note 6: The LTC1159C, LTC1159C-3.3, and LTC1159C-5 are not tested

and not quality assurance sampled at – 40

°C and 85°C. These

specifications are guaranteed by design and/or correlation. The LTC1159I,

LTC1159I-3.3 and LTC1159I-5 are guaranteed and tested over the – 40

°C

to 85

°C operating temperature range.
