Today I found at work a printed circuit board with eight LT1013
op-amps all dated 1989. It is an unused spare part board for something
trashed a long time ago. As a bonus the single sided copper makes it
easy to unsolder the components with minimal heating.
According to the LT1013 datasheet the offset long term stability is
pretty good: 0.5 uV per month typically for a new device. But even
that (if cumulative) can be a problem in the most demanding
Is it realistic to expect that those 20+ years old op-amps are much
more stable than same type manufactured this year?
