AC? DC? Digital DC? Linear power? What precautions should be taken?

 

It requires DC.
The digital DC supply tends to be noisier than the linear DC supply, so which to use depends upon the noise you can tolerate in the DAC current output.
Also the output accuracy depends upon the accuracy and stability of the supply voltage.
