IC operational amplifiers are almost omnipresent in analogue circuit design. On this page I present some work concerning the performance and implementation of ICs.
Operational Amplifier Distortion

A comprehensive measurement series on opamp distortion; currently 59 amplifiers are tested for four basic distortion mechanisms. Be prepared to find substantiall difference amongst various parts. New devices will be added as soon as time permits.
There has been discussions of this document at several internet forums and blogs which might be of interest as well:
