Note 10:
Hysteresis in offset voltage is created by package stress that operating temperature range of – 40°C and 85°C. differs depending on whether the IC was previously at a higher or lower
Note 5:
The LT1168AC/LT1168C are guaranteed to meet specified temperature. Offset voltage hysteresis is always measured at 25°C, but performance from 0°C to 70°C. The LT1168AC/LT1168C are designed, the IC is cycled to 85°C I-grade (or 70°C C-grade) or – 40°C I-grade characterized and expected to meet specified performance from – 40°C (0°C C-grade) before successive measurement. 60% of the parts will to 85°C but are not tested or QA sampled at these temperatures. The pass the typical limit on the data sheet. LT1168AI/LT1168I are guaranteed to meet specified performance from – 40°C to 85°C. 1168fa 5
