Thermocouple Signal Conditioning Using the AD594/AD595

Thermocouple Signal Conditioning Using the AD594/AD595


One of the most widely used devices for temperature measurement is the thermocouple. Whether in an industrial, commercial or scientific application, a thermocouple offers a cost effective solution to temperature measurements in many environments over wide temperature ranges. Unfortunately, their basic principles are often misunderstood resulting in serious measurement errors.

This application note will review thermocouple fundamentals and illustrate circuit designs for thermocouple signal conditioning using the AD594/ AD595 monolithic IC.
