SM6451BV NIPPON PRECISION CIRCUITS INC.

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 fr
