Specifications subject to change without notice.
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.
Input Offset Voltage specifications are guaranteed after 5 minutes of operation at T
Bias Current specifications are guaranteed at maximum at either input after 5 minutes of operation at T
every 10 C.
Matching is defined as ther difference between parameters of the two amplifiers.
Defined as the maximum safe voltage between inputs, such that neither exceeds 10 V from ground.
