Last week we wrote about a Maxim app note about high precision temperature measurement with thermocouples. At Jim’s request we found a more in-depth intro to thermocouples.
This app note from Linear Technology covers everything you ever needed to know about thermocouples. Learn how thermocouples were discovered, and how to build very elaborate and highly accurate amplifiers.
Via the comments. Thanks Jim!

I wish all app notes had a cartoon at the end :3
Yes, this app note is written by the venerable Jim Williams who passed away last year. Mr. Williams was the author of many famous application notes at both National Semiconductor (now owned by Texas Instruments) and Linear Technology Corp. (LTC). There is a very nice site revisiting his work here:
