Hey Brian, 

I am sorry I missread your question. I thought they are already considering a power stage with our DAC controlling it. 

Typically we dont recommend to use our DAC as a power source. The DAC can drive up to 50mA of current at 5V range. 

I was quickly looking through the DS it looks like thye might need a higher voltage to drive it. Would you mind sending me an email, we might have better devices that we can suggest. 

Thank you, 

Illia Volkov
