Im looking at building an op amp circuit which takes a small AC voltage and outputs a DC voltage for an AD Convertor. I've done a search but I don't really understand the theory that well and how to pick the correct op amp.
Input:
45mVpp
50Hz
Output:
0-4.096v (4-5v will do) DC
I've designed the following circuit in multisim using filter pro for the circuit, however when I do it in altium with real components it doesn't seem to work to well.
**broken link removed**
So I guess Im asking what the best way to create this circuit is, and how do I pick the correct op amp for the specification? we haven't picked a power supply yet so anything from +-5 - 15v should be ok.
