Is there a way to control this board with out the SDP card? From the schematics, it looks like Vdd and Vss only go to the output opamps.  I want to run this independent of the USB bus and straight from our own controller using SPI. I do not want to power it using USB because the signal gets very noisy, especially when the computer is charging.
