AD9106: Offset voltage

Hey everyone,

I'm currently building a waveform generator based on the AD9106 chip. Unfortunately the AD9106 in pair with my output circuit (see Image) produces an voltage offset after converting the differential current signal into a single-ended voltage signal. Even if I hit the Reset button on my PCB, the offset stays the same. Supply voltage for the OP-amp is +/- 5V. I already testet the output circuit and it behaves as expected. Therefore I guess that there is a current coming from the AD9106 that shouldn't be there usually. Does anybody know a solution for this issue?

 

Thanks in advance!
