Using SPI to communicate to a DAC

Using Arduino Project Guidance
1

Good evening,
I have been working on a project recently that involved changing the voltage output of a DAC. I have tried to program the arduino myself, but nothing seems to work. I am using an arduino uno. If anyone could please offer any help, I would greatly appreciate it.I will attach the data sheet of the DAC I am working with.

Have you tried writing to and reading from the control register? That is page 17 of you datasheet. It appears the default state of the DACs is powered down.
