I don't have a LM6132/LM6134 for this project. I am wondering about substituting LM6142. From looking at the datasheet (to a newbe) it looks like the main thing that I have to do is make the Op Amp exactly a doubler of the signal from the temperature sensor. Other than that it looks like it should work. So the LM6134,CMRR 100 dB, Gain 100 dB with RL = 10k/ LM6142 CMRR 107dB, Gain 108dB with RL = 10k(see attachments). Notice the table link in the doc.
Can this be done? Should it be done? What is the formula to calculate this? Is it as sinple as 100 db/10K= ohms per db, and 108 db/10K= ohms per db?
Thanks
