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: IB and IOS readings are extrapolated to a warmed-up temperature

from 25

°C measurements and 32°C characterization data.

Note 4: Current noise is calculated from the formula:

in = (2qIB)1/2

where q = 1.6 • 10 –19 coulomb. The noise of source resistors up to 200M

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 AV = –1; input signal is ±7.5V, output

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.
