Re: A way to improve ADC signal to noise ratio (an idea)

Could you elaborate? It looks like the thread you posted is intended to lower power consumption at the expense of increase noise of ADC: + ADC power can be controlled by the FSM instead of software. This allows the ADC to + be shut off when it is not working leading to lower power consumption. Howev...

A way to improve ADC signal to noise ratio (an idea)

I have been playing for a while with ESP32 ADCs, and clearly they are suffering from internal cross talk from other digital circuits. The ADC itself have decent linearity, but the noise is way above expectations. The common way to deal with this is to shut down as much periphery as you can, so proba...
