Note 1: Absolute Maximum Ratings are those values beyond which the life
a device may be impaired.
Note 2: Specifications over the –40°C to 85°C temperature range are
assured by design, characterization and correlation with statistical process
controls.
Note 3: Tests are performed as shown in the configuration of Figure 3.
Note 4: Tests are performed as shown in the configuration of Figure 1 for
IF input.
