The worthy but modest potentiometer continues to be seen as the cost-effective way to adjust signal levels into and out of professional and consumer products. However, the twists and turns of the ...

Digital potentiometers (pots) offer advantages for audio volume (gain) control applications and can replace bulky mechanical pots, especially in handheld portable devices such as MP3 players, PDAs, ...

This design idea details how a standard volume control can be replaced by its solid-state equivalent. Digital potentiometers are often advertised as replacements for rotary volume controls. To ...

In low-end audio systems, digital potentiometers can be used as audio attenuators or amplifiers (Fig. 1). Unfortunately, a large change in volume at an arbitrary time can cause an abrupt discontinuity ...

We connected the DS1807 to the Bus Pirate universal serial interface tool as shown in the table, the same basic principals apply to any custom configuration. We used the Bus Pirate’s 5volt power ...

[Stephen Woodward] is familiar with digital potentiometers but is also familiar with their limitations. That spurred him to create the PWMPot which performs a similar function, but with better ...
