HARA TERISTICS

measured at

±5V.

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

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.
