This is volume control that cab be used for replacing your manual volume control in a stereo amplifier. This circuit is types for digital controller. This circuit is control by DS1669. Here’s the figure of the circuit.
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. This circuit has low-cost alternative to mechanical control. Wide differential input voltage range between 4.5 and 8 volts. The circuit is extremely simple and compact requiring very few external components. The power supply can vary from 4.5V to 8V. Applications include volume, tone, contrast, brightness, and dimmer control.
