I’m want to use DUE’s 12 bit ADC resolution in a color organ project that samples and runs filter algorithms at 10KHz for 32 mS blocks, loads a WS2811 LED string, then returns to sampling for another 32mS. It works rather well, but the dynamic range is limited by 3 or 4 LS bits of noise in the raw …

DUE’s power up sequence seems to cause, or avoid, ADC noise
