The thermocouple is a simple, widely used component for
measuring temperature. This article provides a basic overview
of thermocouples, describes common challenges encountered
when designing with them, and suggests two signal conditioning
solutions. The first solution combines both reference-junction
compensation and signal conditioning in a single analog IC for
convenience and ease of use; the second solution separates the
reference-junction compensation from the signal conditioning to
provide digital-output temperature sensing with greater flexibility
and accuracy.
