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.
