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.

Speech Pitch Controller using MSM6322GSK

That circuit uses the MSM6322GSK which is only available in small 24 pin plastic SOP style package. A speech pitch converter IC that operates in real time and requires very few external components. It has a microphone preamplifier and line level input and the output requires only a single transistor to directly drive a loudspeaker. As well as the microphone preamplifier, the IC contains a 4th order low pass filter on input and a 3rd order low pass filter on output. In addition there is a build-in 8-bit A/D converter and 9-bit D/A converter. [...]

Digital Volume Control by DS1669

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.
