Community Translation: FM4 ADCの使用上、ハードウエアの懸念点‐
In order to use ADC properly, the reference voltage (Analog Voltage Reference High (AVRH) /Analog Voltage Reference Low (AVRL)) is important. It is necessary to suppress the reference voltage swing and avoid noise on power and ground lines as much as possible.
