Note 8: 0.1Hz to 10Hz noise can be inferred from the 10Hz noise voltage Note 2: Typical parameters are defined as the 60% yield of parameter density test. See the test circuit and frequency response curve for 0.1Hz distributions of individual amplifiers; i.e., out of 100 LT1125s (or 100 to 10Hz tester in the Applications Information section of the LT1007 or LT1124s) typically 240 op amps (or 120) will be better than the indicated LT1028 data sheets. specification. Note 9: This parameter is guaranteed but not tested. Note 3: This parameter is 100% tested for each individual amplifier. Note 10: The LT1124C/LT1125C and LT1124AC/LT1125AC are guaranteed Note 4: This parameter is sample tested only. to meet specified performance from 0°C to 70°C and are designed, Note 5: This parameter is not 100% tested. characterized and expected to meet these extended temperature limits, Note 6: The inputs are protected by back-to-back diodes.
