Hi all,

 

I checked following thread and others.
AD2S12xx SIN/COS input CMV query

AD2S12xx SIN/COS input CMV query 

 

AD2S1205/AD2S1210 Common-Mode Voltage

https://ez.analog.com/message/124315?commentID=124315#comment-124315 

 

They say, the AD2S1210 SIN/COS CMV is REFOUT/2 = 1.25V +/- 100mV.

 

But our customer's EVB(EVAL-AD2S1210SDZ) which is evaluating now is,
SIN/COS is about 1.6V.
SINLO/COSLO is about 0.8V.

 

 

Is it correct spec?
CMV is unbalance.

 

Best regards,
sss
