The q denotes the specifications which apply over the full operating
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: in = (2qIb)1/2, where
q = 1.6 x 10–19 coulomb. The noise of source resistors up to 1GΩ
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.
