Tell us about yourself!
I see my first overall mistanke, it is 3 10K resistors and not 3 3K3 resistors, I'll change my test and try again, thanks for you quich answer. Back to drawing board :)
Hi Thomas, very nice work! :)I have a little problem, when I look at U3C and make a calculation I get a GAIN of 10. The text below and in the schmatics states a GAIN of 4.I made at setup simuler to your setup. It gives a GAIN of 10. To get a GAIN of 4 R10 has to be 3K3.Did you change to setup?
Apple, Linux or PC, no references at all, I guess Apple :)
