The LC-filter to the AVCC pin is recommended in all datasheets. Recommended values are 100nF and 10µH. But what about the inductor DC resistance? Wrong value here will have great impact of the efficency and/or the frequency responce. Also, there is a size matter, the smaller size of the inductor, the higher DC resisistance.
Does anyone have any recommendations of the maximum DC resistance of the inductor?
