WebThe minimum input impedance of the analog pin is thus RADC. In the datasheet the maximum value of RADC is specified instead of a typical value, so that the user can calculate the affect of external resistance on sampling. This is explained in Section 4.4. 2.2 ANALOG MULTIPLEXER The ADC can have several analog input pins. Web14 mei 2024 · I cropped that picture from here, that article assumes a 10-bit ADC so it uses a maximum value of 1024, while I think it must be 1023. I think what they mean with 1024 is the possibilites not maximum value of an n-bit ADC. If it's 1023 at the denominator, you expect 1023 to be generated at EXACTLY Vref at input.
