Gday all, I have a need to interface a thermo couple to a pic, I believe that there is a special purpose ic out there that not only scales but also corrects the output to allow for nonlineararity and presents you with a voltage/temp value or better still I2C of SPI. Anybody know its name/manufacture?

After three hours I asked him to summon up the soul of Jimi Hendrix and requested All Along the Watchtower. You know, the guy's been dead twenty years but he still hasn't lost his edge' Mulder
