There are several ways to power supply your board (in addition to the native USB and programming port, which are not super stable supplies since they come from the PC), and some may be "noisier" than others:

However, if you can't remove spikes with an RC circuit from DACx outputs, you can try using an external DAC via SPI : Goggle DUE DAC SPI to find the right tutorial from schianorobotics.
