Features

  • 1) They facilitate direct serial control from a microcomputer of volume (main volume) and tone (bass, treble). DC control is also possible. 2) Volume is produced by a low-distortion, low-noise VCA. Designed to minimize step noise. 3) Input amp can be used for gain adjustment, and matrix surround yields powerful sound. 4) Stable standard voltage supply and built-in I / O buffer mean that few attachments are needed. SSOP32 package designed to save space. FAbsolute maximum ratings (Ta = 25_C) 5) Op.

Audio ICs Serial sound control IC BH3854AS / BH3854AFS The BH3854AS and BH3854AFS are signal processing ICs designed for volume and tone control in CD radio cassettes and other audio products. Their three-line serial control enables them to control volume and tone on the basis of signals from a microcomputer, etc. FApplications CD radio cassettes, mini component stereo systems, car stereos FFeatures 1) They facilitate direct serial control from a microcomputer of volume (main volume) and tone (bass, treble). DC control is also possible. 2) Volume is produced by a low-distortion, low-noise VCA. Designed to minimize step noise. 3) Input amp can be used for gain adjustment, and matrix surround yields powerful sound.
