AD9826 CDS Mode

Question asked by hmp on May 29, 2018

I want to use AD9826 in 2 channel CDS mode. I used your recommended circuit configuration on datasheet.

I applied clock inputs as Fig. 3 and checked voltage level at the VINR and VING were 4V.

When I got the data from adc, it was too small signal.

When I try to 2ch SHA mode, AD9826 works fine and I get desired value of the signal.

I could adjust offset and gain too.

It means the interface between MCU and AD9826 is correct.

Could you please advise me how could I use CDS mode.
