AD5328 stops converting after some time

Hello,

 

I'm using the AD5328 DAC together with the STM32L152 Discovery board. The microcontroller sends some data to the DAC through SPI and the DAC converts this. It works fine, but after some time it stops converting and it keeps its previous value.

 

I have the LDAC pin tied to VDD and before every conversion I set the LDAC bits to low. Could this be the problem? What is the best way to set the LDAC pin and bits?

If this is not the issue, any other ideas? I can post some code if needed.

 

Thank you for the help.
