1
Input Offset Voltage specifications are guaranteed after 5 minutes of operation at T
= +25
°
C.
2
Bias Current specifications are guaranteed at maximum at either input after 5 minutes of operation at T
A
= +25
°
C. For higher temperatures, the current doubles every 10
°
C.
3
Matching is defined as the difference between parameters of the two amplifiers.
4
Defined 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.
