Volume Control Devices
Analog Devices’ audio digital potentiometers provide stereo volume/balance control to replace mechanical potentiometers in audio applications requiring digitally controlled resistors. Wiper position can be controlled through a serial interface, debounced rotary encoder or push-button up/down interface. Features include single or dual potentiometers with log taper and up to 64 taps, up to 45 kΩ end-to-end resistance, stereo volume control, daisy-chaining, and clickless switching. Our volume control devices consume very little power while providing digital accuracy and reliability under flexible, automatic processor control.
