NOTES
1_{Input offset voltage measurements are performed by automated test equipment approximately 0.5 seconds after application of power. E Grade specifications are}
guaranteed fully warmed up.
2_{Long term input offset voltage stability refers to the average trend line of VOS vs. time over extended periods after the first 30 days of operation. Excluding the initial}
hour of operation, changes in V_OS during the first 30 days are typically 2.5 mV. Refer to the Typical Performance Curve.
3_{Sample tested.}
4_{Parameter is guaranteed by design.}
5_{See test circuit and frequency response curve for 0.1 Hz to 10 Hz tester.}
6_{See test circuit for current noise measurement.}
7_{Guaranteed by input bias current.}
Specifications subject to change without notice.
