NOTES
1Input Offset Voltage specifications are guaranteed after 5 minutes of operation at T
A = +25°C.
2Bias Current specifications are guaranteed maximum at either input after 5 minutes of operation at T
A = +25°C.
For higher temperatures, the current doubles every 10
°C.
3Defined as voltage between inputs, such that neither exceeds
±10 V from ground.
4Typically exceeding –14.1 V negative common-mode voltage on either input results in an output phase reversal.
Specifications 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.
