The 
 denotes the specifications which apply over the full operating
temperature range.
Note 1:
  The LT1122 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.
Note 2:
  Settling time is 100% tested for A and C grades using the settling
time test circuit shown. This test is not included in quality assurance
sample testing.

Note 3:
  Input voltage range functionality is assured by testing offset
voltage at the input voltage range limits to a maximum of 4mV (A, B
grades), to 5.7mV (C, D grades).
Note 4:
  Minimum supply voltage is tested by measuring offset voltage to
7mV maximum at 
±
5V supplies.
