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 parameter
distributions of individual amplifiers.
Note 3: I
from 25 C measurements and 32 C characterization data.
Note 4: Current noise is calculated from the formula:
where q = 1.6 • 10
swamps the contribution of current noise.
Note 5: Input voltage range functionality is assured by testing offset
voltage at the input voltage range limits to a maximum of 2.3mV
(A grade) to 2.8mV (C grade).

Note 6: This parameter is not 100% tested.
Note 7: Slew rate is measured in A
measured at 2.5V.
Note 8: The LT1793AC and LT1793C are guaranteed to meet specified
performance from 0 C to 70 C and are designed, characterized and
expected to meet these extended temperature limits, but are not tested at
– 40 C and 85 C. The LT1793I is guaranteed to meet the extended
temperature limits. The LT1793AC and LT1793AI grade are 100%
temperature tested for the specified temperature range.
Note 9: The LT1793 is measured in an automated tester in less than one
second after application of power. Depending on the package used, power
dissipation, heat sinking, and air flow conditions, the fully warmed-up chip
temperature can be 10 C to 50 C higher than the ambient temperature.
