"Nettet16. apr. 2024 · How does an ADC work? A good way to look at the working of an ADC is to imagine it as a mathematical scaler. Scaling is basically mapping values from one range to another, so an ADC maps a voltage value to a binary number. What we need is something that can convert a voltage to a series of logic levels, for example in a register. " - How sar adc works
