Unformatted text preview: inverting amplifier. The instrumentational amplifier is a good device for removing common mode noise. Get the LM324 quad op-amp IC (with its data sheet), 6 resistors (100k) and a thermocouple. Build the circuit shown below. Connect the thermocouple terminals to V 1 and V 2 . Choose R2 to amplify the input signal about 1,000 times (900 is ok). Read the output voltage from V o using a multimeter. This is the noniverting Op-amp circuit (just for your knowledge)....
