Audio Variable Volume IC
OVERVIEW
The SM6451BV 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
SM6451BV devices to be connected and individually controlled over the 3-wire control interface from a single
CPU. It is available in 16-pin VSOP packages.
