I wonder why this happens to my ad9613.
The problem is that ADC can get first channel data correctly. The problem is that I cannot get the data from channel 2, even if I get the data without doing anything(means nothing goes into ADC),
the data noise is over 200mv.
(This data is channel 2 data, using Labview with hsc-adc-evalcz driver, nothing going in to channel 2).
So, my question is , what may cause this problem to ad9613? Are there any patterns that cause this kind of problem?
I connected ad9613, referenced with ug-293. the set of ad9613 is all default.
