I have the Analog Devices, Inc., "Data Converter Reference Manual", Volumes I & II, 1992 edition. These are big and heavy (3 pounds apiece). I am no longer interested in keeping these manuals around. I will be willing to send these to anyone who is willing to pay for the shipping (via Media Mail). It looks like the cost will be a little over $5, so the first person with $5 who wants these manuals can get them. Thanks and I'll be checking this list to see who, if anyone, is interested.
