LT1122
ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
Input voltage range functionality is assured by testing offset may cause permanent damage to the device. Exposure to any Absolute voltage at the input voltage range limits to a maximum of 4mV Maximum Rating condition for extended periods may affect device (A, B grades), to 5.7mV (C, D grades). reliability and lifetime.
Note 5:
Minimum supply voltage is tested by measuring offset voltage to
Note 2:
The LT1122 is measured in an automated tester in less than one 7mV maximum at ±5V supplies. second after application of power. Depending on the package used, power
Note 6:
The LT1122 is not tested and not quality-assurance-sampled dissipation, heat sinking, and air flow conditions, the fully warmed up chip at –40°C and at 85°C. These specifications are guaranteed by design, temperature can be 10°C to 50°C higher than the ambient temperature. correlation and/or inference from –55°C, 0°C, 25°C, 70°C and/or 125°C
Note 3:
Settling time is 100% tested for A- and C-grades using the settling tests. time test circuit shown. This test is not included in quality assurance sample testing.
