We are facing the issue of AD7265, when intend to read both ADC data on one Dout line, as shown in Figure 42 of datasheet,

reading result is unstable, in other words, sometimes(maybe around 30~50%) both data are successful,

but either of them or both of them are wrong(apart from voltage supplied to VA1/VA2/VB1/VB2) in many times.

It seems problem occurs in random and irregularly.

By thinking we can have correct conversion results in nearly half rate, we believe basic operation probably be OK.


Could you please instruct what points should we checked ?

Any of your comments and advises are very much appreciated.


Best Regards,
