Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 7:
Slew rate is measured in AV = –10; input signal is ±1V, output of a device may be impaired. measured at ±5V.
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 to distributions of individual amplifiers; i.e., out of 100 LT1127s (or 100 10Hz tester in the Applications Information section of the LT1007 or LT1126s) typically 240 op amps (or 120) will be better than the indicated LT1028 datasheets. specification.
Note 9:
This parameter is guaranteed but not tested.

Note 5:
This parameter is not 100% tested. 85°C. Guaranteed I grade parts are available. Consult factory.
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. 11267fa 4
