Digital Volume Control

For those who want to create their own sound system itself, it is a well-destination circuit diagram. These circuits are normally used Control Pot volume increase volume reduction after a few days during which “khyasa - khyasa “is the word. This digital volume Control there is no possibility of this kind of problem. Circuit diagram say simple three IC component, two ceramic capacitors and two double function switch pusa. 7805 ICT acts as a voltage regulator. Usually 1 V or V power supply is used, and more. But to control the volume using 5 ICT supply is so 7805. The other two being DS1669 Digital Pot IC IC circuitry. Sw 1a, 1b volume up and Sw 2a, 2b has been used down the volume. There are some push switch acts as the one between these two, with two switches Sw 1a, 1b, and Sw 2a, 2b will not connect. If you can run and operate the four switches single push Left and Right channels to control the volume separately.
