NOTES
1Input 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.
2Long term input offset voltage stability refers to the average trend line of V
OS vs. time over extended periods after the first 30 days of operation. Excluding the initial
hour of operation, changes in VOS during the first 30 days are typically 2.5
mV. Refer to the Typical Performance Curve.
3Sample tested.
4Parameter is guaranteed by design.
5See test circuit and frequency response curve for 0.1 Hz to 10 Hz tester.
6See test circuit for current noise measurement.
7Guaranteed by input bias current.
Specifications subject to change without notice.
