General Description
SM6451B General Description
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.
