Digital Volume Control circuit

The series is a digital volume control using six discrete ICs, including a 5V regulator. IC1 (555) is configured to function as astable flip-flop. Frequency or period can be adjusted by proper choice of resistors R44, R45 and capacitor C6 combination. This is the period to 0.3 seconds.

IC2 is a regulator of the calculation of the volume up or down. In this series up mode is used to improve the volume and mode down is used to reduce the volume. IC3 and IC4 are 16-channel analog multiplexer that read more
