Hi,
I've been trying to put together a simple one stage amp for a K-type thermocouple on a breadboard, without success. I've tried a TL072 and a TL082 with the 200mV setting on the oscilloscope but it only shows noise. I'd like to have something like 10mV per 1 degree C.
Is it it possible to do this with just one amp stage or do I need two or more? Should I use inverting or non-inverting configuration? Can it be done with just a single rail power supply?
If someone has a circuit for this purpose above mentioned op-amps I'd appreciate if you post it here.
Thanks!
