temperature range.
Note 1: Typical parameters are defined as the 60% yield of distributions of
individual amplifiers; i.e., out of 100 LT1457s (200 op amps) typically 120
will be better than the indicated specification.
Note 2: This parameter is tested on a sample basis only.
Note 3: Current noise is calculated from the formula: i
q = 1.6 x 10
swamps the contribution of current noise.

Note 4: This parameter is not 100% tested.
Note 5: Gain-Bandwidth product is not tested. It is guaranteed by design
and by inference from the slew rate measurement.
Note 6: The LT1457 is not tested and not quality-assurance-sampled at
– 40 C and at 85 C. These specifications are guaranteed by design,
correlation, and/or inference from 0 C, 25 C, and 70 C tests.
