I use AD5628ACPZ-2-RL7 DAC in my device and I can't make it works stable. Some times all DACs go down. I do not know reason why.

 

- I use 0.1 uF and 10uF between Reference and GND.

- 22uF tantal and 0.1uF between Power to GND.

- CLR pin is on the GND.

- SPI is connected by 30 cm wires directly.

 

Please Help me to find reason and make it work stable...
