    This application report describes a low-cost, thermocouple-based, temperature measurement system featuring high-noise immunity and electrical isolation between the analog and digital circuits. Unlike conventional designs employing analog cold junction compensation, in this design the thermocouple is connected directly to the differential inputs of an INA326 instrumentation amplifier.
