Two Input AND Gate

Mounted on base, with 4 mm colour coded sockets, with circuit diagram printed for demonstration. Thermistor is mounted above the base to avoid the damage from heat.

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.
