Digital Volume Control by DS1669
This entry was posted on Saturday, April 19th, 2008 at 6:16 am and is filed under Electronic Control, audio article.
This circuit could be used for replacing your manual volume control in a stereo amplifier. In this circuit, push-to-on switch S1 controls the forward (volume increase) operation of both channels while a similar switch S2 controls reverse (volume decrease) operation of both channels. A readily available IC from Dallas semiconductor, DS1669 is used here.
