Digital Volume Control Circuit

The heart of this digital volume controller DVC circuit is IC2 4067, 16-channel analog multiplexer.
Because the 1kΩ has been connected between every input and output, the multiplexer can act like a potentiometer. The total resistance is 15kΩ . You can use different values for the resistor to obtain a different characteristic. The current consumption is 1mA.
