Circuit Diagram-Digital Volume Control

Circuit Diagram-Digital Volume ControlCircuit Diagram-Digital Volume Control

This ambit could be acclimated for replacing your chiral aggregate ascendancy in a stereo amplifier. In this circuit, push-to-on about-face S1 controls the advanced (volume increase) operation of both channels while a agnate about-face S2 controls about-face (volume decrease) operation of both channels.

A readily accessible IC from Dallas semiconductor, DS1669 is acclimated here.

FEATURES:

* Replaces automated capricious resistors

* Electronic interface provided for agenda as able-bodied as chiral control

* Wide cogwheel ascribe voltage ambit amid 4.5 and 8 volts

* Wiper position is maintained in the absence of power

* Low-cost another to automated controls

* Applications accommodate volume, tone, contrast,brightness, and dimmer control

The ambit is acutely simple and bunched acute actual few alien components. The ability accumulation can alter from 4.5V to 8V.
