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: Differential input voltages greater than 1V will cause excessive

current to flow through the input protection diodes unless limiting

resistance is used.

Note 3: Typical parameters are defined as the 60% yield of parameter

distributions of individual amplifiers; i.e., out of 100 LT1114s (or 100

LT1112s) typically 240 op amps (or 120) will be better than the indicated

specification.

Note 4: This parameter is guaranteed by design and is not tested.
