FOUR_THERMOCOUPLE_MULTIPLEXING

Low power dissipation in DG306 analog switches means lower offset voltages added to thermo-couple voltages by silicon in contact with aluminum in switches. Thermocouples are switched differentially to instrumentation amplifier driving meter, in order to cancel thermal offsets due to switch.- Analog Switches and Their Applications, Siliconix, Santa Clara, CA, 1976, p 7-87.
