SM6451B

Audio Variable Volume IC

OVERVIEW

The SM6451B is a 3-wire serial-controlled electronic variable volume IC for audio applications. It provides

electronic volume control for a stereo system (left and right channels), and independent channel attenuation

and muting, with greatly enhanced digital zip noise suppression. The chip address function allows up to four

SM6451B devices to be connected and individually controlled over the 3-wire control interface from a single

CPU. It is available in 16-pin TSSOP packages.
