Analog to Digital Converter
The ADC unit converts an analog signal to a 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 volts 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 analog voltage.
