MAX5408EEE+T

The MAX5408EEE+T is a dual, audio log taper digital potentiometer in 16 pin QSOP package. It is a dual potentiometer with one wiper per potentiometer. Each potentiometer has 32-tap points and the SPI compatible serial interface controls the wiper positions. The MAX5408 zero-crossing detect feature minimizes the audible noise generated by wiper transitions. It is used in stereo volume control, fading and balancing stereo signals and mechanical potentiometer replacement.
