measured at ±2.5V.

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 data sheets.

Note 9: This parameter is guaranteed but not tested.

Note 10: The LT1124C/LT1125C and LT1124AC/LT1125AC are guaranteed

to meet specified performance from 0°C to 70°C and are designed,

characterized and expected to meet these extended temperature limits,

but are not tested at –40°C and 85°C. The LT1124AI and LT1124I are

guaranteed to meet the extended temperature limits.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: Typical parameters are defined as the 60% yield of parameter

distributions of individual amplifiers; i.e., out of 100 LT1125s (or 100

LT1124s) 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
