What people say. Recommended for sizing antialiasing and charge bucket filters correctly to handle ADC kickback and noise.

On “[STM32F3] Help me understand the variation in accuracy of STM32 ADCs - why is sample time such a strong determinant of measured value?”

You probably have a combination of kickback and noise that should actually be filtered, you do want what’s called an antialiasing filter but it needs to be sized correctly link to this video The full series link to this video
