Hello,
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?
thanks
