The MAX5411EEE+ from Maxim Integrated Products is a dual, audio log taper digital potentiometer in 16 pin QSOP package. This potentiometer has 32-tap points and replaces mechanical potentiometers in audio applications requiring digitally controlled resistors. The MAX5411 are dual potentiometer with two wipers per potentiometer. The SPI compatible serial interface controls the wiper positions. It has factory set resistance of 10Kohm per potentiometer. A zero crossing detect feature minimizes the audible noise generated by wiper transitions. The MAX5411 has nominal temperature coefficients of 35ppm/°C end to end and 5ppm/°C ratiometric. Typical applications include stereo volume control, fading and balancing stereo signals, mechanical potentiometer replacement.
