ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at VS = ±15V, 0°C ≤ TA ≤ 70°C, unless otherwise noted.
Note 7: Slew rate is measured in AV = –10; input signal is ±1V, output
measured at
±5V.
Note 8: 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 9: This parameter is guaranteed but not tested.
Note 10: The LT1126/LT1127 are designed, characterized and expected to
meet these extended temperature limits, but are not tested at –40
°C and at
85
°C. Guaranteed I grade parts are available. Consult factory.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: 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 3: This parameter is 100% tested for each individual amplifier.
Note 4: This parameter is sample tested only.
Note 5: This parameter is not 100% tested.
Note 6: 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.
