Hi there!... the aim of my project is to get 8 temperatures using 8 thermocouples (from 0 C - 1000 C), 8 AD595 for each one to get mV signals from the thermocouples, and then introduce them in a microcontroller to show them in a LCD. I was thinking about using a MUX instead of 8 AD595 (they're expensive) but I don't know which one could work with uV from the thermocouples... =( ... most of them introduce noise...
