Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LTC4012C-3 is guaranteed to meet performance specifications
over the 0°C to 85°C operating temperature range. The LTC4012I-3 is
guaranteed to meet performance specifications over the –40°C to 125°C
operating temperature range.
