Note 7: 0.1Hz to 10Hz noise can be inferred from the 10Hz noise voltage density test. See the test circuit and frequency response curve for 0.1Hz to 10Hz tester in the Applications Information section of the LT1007 or LT1028 datasheets. Note 8: This parameter is guaranteed but not tested. Note 9: The LT1126 and LT1127 are not tested and are not quality assurance sampled at –40 °C and at 85°C. These specifications are guaranteed by design, correlation and/or inference from – 55 °C, 0°C, 25°C, 70 °C and/or 125°C tests. The • denotes the specifications which apply over the full operating temperature range. Note 1: Typical parameters are defined as the 60% yield of parameter distributions of individual amplifiers; i.e., out of 100 LT1127s (or 100 LT1126s) typically 240 op amps (or 120) will be better than the indicated specification. Note 2: This parameter is 100% tested for each individual amplifier. Note 3: This parameter is sample tested only. Note 4: This parameter is not 100% tested. Note 5: The inputs are protected by back-to-back diodes. Current limiting resistors are not used in order to achieve low noise. If differential input voltage exceeds ±1.4V, the input current should be limited to 25mA.
