The q denotes specifications that apply over the full specified

temperature range.

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: Does not include the effect of the external gain resistor RG.

Note 3: This parameter is not 100% tested.

Note 4: The LT1920C is designed, characterized and expected to meet the

industrial temperature limits, but is not tested at – 40°C and 85°C. I-grade

parts are guaranteed.

Note 5: This parameter is measured in a high speed automatic tester that

does not measure the thermal effects with longer time constants. The

magnitude of these thermal effects are dependent on the package used,

heat sinking and air flow conditions.

Note 6: Typical parameters are defined as the 60% of the yield parameter

distribution.
