I designed a 4CH op-amp configuration using AD8004. I used their recommended values to get best performance. But when I input a signal into any channel I get half of the amplitude as o/p.
My input signal is 1Vp-p. As soon as I connect it to the i/p side, the i/p drops to 510mVp-p (as expected), but the output is at 510mVp-p as well, I adjusted my P1 so that P1+R92 = R93.
Attached is a screenshot of the datasheet and my design. Any ideas?
I am pretty sure. When I deleted all the rest of the stuff from the other 3 channels to take a screenshot, I accidentally removed the gnd on this too. But, on the actual board it is connected to ground.
I don't think so, this is running at ±5V supply and more over my required gain is +2 which gives an output of 2Vp-p. My actual input itself is 1Vp-p. Let me know if you think otherwise.
