Re: opamp (3v power use)
Hi,
the ac part is 0.2 volt and i want to amplify it by factor 11. So I get 2.2v at the output.
What happens if i connect the virtual ground to input? E.g. the signal is not around 0v, it is at 1.5 +- 0.2...
Is the dc part amplified,too? I only have 3v, so there should be a large cut of. I Or amplifieng with factor 10 is not possible with dc 1.5v.
Why do I need the capacity between virtual ground and ground, and why 100uF? Please tell me,
Patrick
