The SM6451A/B 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 SM6451A/B devices to be connected and individually controlled over the 3-wire control interface from a single CPU.
