The MAX5408-MAX5411 dual, logarithmic taper digital potentiometers, with 32-tap points each, replace mechanical potentiometers in audio applications requiring digitally controlled resistors. The MAX5408/MAX5410 are dual potentiometers with one wiper per potentiometer. The MAX5409/MAX5411 are dual potentiometers with two wipers per potentiometer (see Functional Diagram). An SPI™-compatible serial interface controls the wiper positions. The MAX5408- MAX5411 have a factory-set resistance of 10kΩ per potentiometer. A zero-crossing detect feature minimizes the audible noise generated by wiper transitions. The MAX5408-MAX5411 have nominal temperature coefficients of 35ppm/°C end-to-end and 5ppm/°C ratiometric. The MAX5408-MAX5411 are available in 16-pin QSOP and 16-pin thin QFN packages and are specified over the extended temperature range (-40°C to +85°C).
Applications
- Fading and Balancing Stereo Signals
- Mechanical Potentiometer Replacements
