LT1711/LT1712

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

of a device may be impaired.

Note 2: The LT1711C/LT1712C are guaranteed to meet specified

performance from 0

°C to 70°C. They are designed, characterized and

expected to meet specified performance from – 40

°C to 85°C but are not

tested or QA sampled at these temperatures. The LT1711I/LT1712I are

guaranteed to meet specified performance from –40

°C to 85°C.

Note 3: The negative supply should not be greater than the ground pin

voltage and the maximum voltage across the positive and negative

supplies should not be greater than 12V.
