MAX5486 Overview
Description
The MAX5486 dual 40kΩ logarithmic taper volume control features a debounced pushbutton up/down interface that controls volume and balance in audio applications. Each potentiometer has 32 log-spaced tap points with a buffered wiper output to replace mechanical potentiometers.
Key Features
- a debounced pushbutton up/down interface that controls volume and balance in audio applications
- Each potentiometer has 32 log-spaced tap points with a buffered wiper output to replace mechanical potentiometers
- A mode-indicator LED output indicates volume or balance control
- Five integrated LED drivers indicate volume level or balance settings, depending on the status of the mode indicator
- Use the MAX5486 digital inputs with momentary contact single-pole/single-throw (SPST) pushbutton switches
- Each input includes internal debounced circuitry and a pullup resistor to VLOGIC
- The MAX5486 advances the wiper setting once per button push
- Maxim’s proprietary SmartWiper™ control eliminates the need for a microcomputer to increase the wiper transition rate
- All of the MAX5486’s pushbutton inputs are debounced
- The mute input allows a single pushbutton to change between volume control and the -90dB (typ) mute setting
