I have to amplify a video signal coming from a CCD array, and also to shift/offset the signal down by about 0.5V.
I found this site with a schematic: http://www.daycounter.com/Circuits/OpAmp-Level-Shifter/OpAmp-Level-Shifter.phtml
The problem is that I can't amplify with it... If I shift down, I loose signal strength, then I amplify it, and I'm back to square one, because if amplifies the "shift" also...
I am using an AD8041 op-amp for this.
I would like to use a potentiometer to manually adjust the shift, and also the amplification.
Can anyone help me with this please?
I attached a screenshot of the signal I get.
