Thanks, Steve. The "Instrument Amplifier Handbook" was only a first rough draft of my intended book. While at Burr-Brown it became clear that, at that time, instrumentation amplifiers were not well known or understood by analog designers. Op amps had become familiar by then and much literature, such as Walter Jung's "Op-Amp Cookbook", was available to guide a user in their applications. Little was available for instrumentation amplifiers.
I was writing it when BB was acquired by Texas Instruments. The TI policy of publications was more restrictive than at BB, requiring reviews and approval by appropriate groups before proceeding. No one at TI was willing to devote any time to doing it. The project fell into limbo and somehow a copy of the draft that had been sent to a BB customer to help him with his circuit fell into the Internet. Now the "book" is all over the 'net.
There may still be some useful information in my rough draft but it is pretty dated by now. I've retired to do some consulting and building a race car so I'm not going to revise it now. Someone else might want to take the IA Handbook idea and expand and update it. They have my Blessing. :)
Thanks for posting. This shows that analog stuff certainly is not trivial, eh, well, that it mostly goes wrong when you do not think about all the nasty influences. Anyway, I still do love this stuff and try to earn some money with it ;-)
