Digital Volume instead of a rotary press using IC DS1669


This is the Digital Volume Push button, which will replace Volume traditional rotation.With simple circuits.Using only a single IC that is at the heart of the work that is IC1 number DS1669.This circuit uses only one input signal input via pin 1 of IC1,Can be used.The switches S1 and S2 is off by press release on the increase and decrease sound volume.When pressing the switch S1 will increase the volume.And when I press the switch S2 to lower the volume.The signal output from the pin 6 will be used to control amplifier another one.
