Thermocouple Temperature Control

  
This control, with zero-voltage load switching, uses a CA3130 BiMOS op amp and a CA3079 zero-voltage switc

h. The CA3130, used as a comparator, is ideal because it can "compare" the low voltages generated by the thermocouple to the adjustable reference voltage over the range of 0 to 20 mV.
