I'm very new at this. Just started playing around with an op amp last week. I have very basic knowledge from a couple courses, but that was also a while ago.
I'm trying to amplify a small voltage (about 0-10mv from a thermocouple). I looked at some schematics & data sheets to try & design my circuit, but somewhere along the way I definitely goofed because I'm getting totally unexpected output values.
The voltage output is about 7.5v with 0v input (grounded), using a 9v source. Am I saturating the Op Amp by trying to amplify the signal too much? What is the max amplification for a typical Op Amp, and what are good resistor values to use for R1 and RF (shown in the attached diagram).
Thanks in advance!
