I need help with this one. I'll give parts needed and a description of what I need.
Parts:
1 op amp
1 cap
Resistors
1 POT
Can you draw me a noninverting amp that will take a 500mV p-p low level signal and amplify it to 100mV p-p to 2V p-p (adjustable)
I was just wanting to see what any of you guys or girls come up with. I want to compare it to mine and see if mine is correct or not.
The trouble I have, is that in my mind I don't think you can get out 100mV p-p. Mainly because gain is determined by RF/R1 +1 right. So even if you had a gain of .1 on the inverting, +1 you would get 1.1. With an output voltage of .550mV p-p.
After thinking about it for awhile, I finally came up with putting a voltage divider on the noninverting input. If I am right, I don't know. That's why I am asking you.
Thanks.
