WebJun 5, 2024 · To understand the ADC in a better way, let us look at an example. Let us say we have an input signal which varies from 0 to 8 volt, and we use a 3-bit ADC to convert this signal to binary data. A 3-bit ADC can represent 2^3 or 8 different voltage levels using 3 bits of data. How convenient! In this case, the ADC maps the data in the following ...
