NOTES
1Input Offset Voltage specifications are guaranteed after 5 minutes of operation at TA = +25°C.
2Bias Current specifications are guaranteed at maximum at either input after 5 minutes of operation at TA = +25°C. For higher temperatures, the current doubles every 10°C.
3Matching is defined as the difference between parameters of the two amplifiers.
4Defined as voltage between inputs, such that neither exceeds ± 10 V from ground.
Specifications shown in boldface are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels. All min and max specifications
are guaranteed, although only those shown in boldface are tested on all production units.
Specifications subject to change without notice.
