Analog to Digital Converter

The ADC unit converts an analog signal to digital signal. When a variable voltage is applied to the input terminals it is converted into a digital output. Therefore, a 3 volt input will correspond to binary 11, and 7 volt will correspond to binary 111. A low frequency AC input signal can be converted into a changing digital value. Use on its own or combined with the DAC to decode back into a stepped analogue voltage.
