OpAmp about its offset voltage aging. Can you specify a long term
stability of the offset voltage ?
We do not explicitly test or specify long term drift on the AD8551 but we do
life testing on all our products. Therefore you can consider the 10uV maximum
specification as the maximum value over the product's life. The second thing to
say is that the AD8551 uses an "auto-zero" technique which continually measures
and nulls out any offset.
