temperature range.

Note 1: Typical parameters are defined as the 60% yield of parameter

distributions of individual amplifiers, i.e., out of 100 LT1169s (200 op

amps) typically 120 op amps will be better than the indicated specification.

from 25

°C measurements and 45°C characterization data.

Note 3: Current noise is calculated from the formula:

1/2

where q = 1.6

swamps the contribution of current noise.

Note 4: Input voltage range functionality is assured by testing offset

voltage at the input voltage range limits to a maximum of 2.8mV.

Note 5: This parameter is not 100% tested.

±2.5V.

Note 7: The LT1169 is designed, characterized and expected to meet these

extended temperature limits, but is not tested at – 40

°C and 85°C.

Guaranteed I grade parts are available; consult factory.

Note 8:

∆CMRR and ∆PSRR are defined as follows:

(1) CMRR and PSRR are measured in

µV/V on the individual

amplifiers.

(2) The difference is calculated between the matching sides in

µV/V.

(3) The result is converted to dB.

Note 9: The LT1169 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.
