The documentation mentions placing a ferrite bead between incoming voltage and the chip's VDDA line. Having limited knowledge of ferrite beads I'm confused as to which bead would work best.
If the DC bias current should be about 20% of the bead's rated DC current, and the STM32L011 will be powered by 3v3, does that mean I should use a ferrite bead rated at around 660 to 700 volts? Or should it be higher? Or lower?
