AD5668 Can set Output one time only

I have a board with 2 AD5668 DACs, one is perfectly working, the other has malfunction.

Both have the same write sequence.


I can switch between the external and internel voltage reference without any problem.

If I try to set VoutA it works one time only. Then the output voltage remains static. After that there is no reaction to further write sequences, I only can set Vref.


I testet a second board with the same layout wich has the same problem.


Does anybody know about that problem?
