Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Typical parameters are defined as the 60% yield of distributions of
individual amplifiers; (i.e., out of 100 LT1058s or, 100 LT1057s, typically
240 op amps, or 120 for the LT1057, will be better than the indicated
specification).
Note 3: This parameter is tested on a sample basis only.
Note 4: Current noise is calculated from the formula:
i
n
= (2ql
b
)
1/2
where q = 1.6 • 10
– 19
coulomb. The noise of source resistors up
to1G swamps the contribution of current noise.
Note 5: This parameter is not 100% tested.
Note 6: Gain-bandwidth product is not tested. It is guaranteed by
design and by inference from the slew rate measurement.
