Hi,
I am trying to convert varying 0.1 to 10V Approx AC input from a Coil to give a 0 to 5v output that I can input an A/D converter on a PIC chip. There are 2X inputs that I compare.
I have tried Op amp circuits, but after many attempts, I can't seem to get consistency.
Is it possible to build a simple input to a 2n3819 Transistor, and perhaps Amplify the current if needed? X2.
Cheers, Camerart.
