SM6452AM/BM NIPPON PRECISION CIRCUITS INC. Audio Variable Volume ICs OVERVIEW The SM6452AM/BM are serial-control electronic variable volume ICs for audio applications. They provide electronic volume control for 6 channels, with independent channel gain, attenuation and muting. They feature enhanced digital zip noise suppression. The serial control options are 3-wire interface (SM6452AM) and I2C bus (SM6452BM). The SM6452AM/BM are available in 24-pin SSOP packages.
