WebSep 13, 2024 · ADC and DAC devices can help to act like that translator. When an ADC sees an analog voltage, its job is to turn the analog voltage into a binary code at a given period of time. This means the ADC will sample the analog voltage at an instant, and then it determines what the value would be in binary on the output side of the ADC. WebThe DAC is simply the feedback portion of the ADC. The basic concept is illustrated here: simulate this circuit – Schematic created using CircuitLab The contents of the dashed boxes is identical at both ends. On the ADC side, the feedback insures that the stream of one-bit samples creates a replica of the analog input signal.
