BH3856FS datasheet pdf

BH3856S / BH3856FS Audio ICs 2-wire serial sound control IC BH3856S / BH3856FS The BH3856S and BH3856FS are signal processing ICs designed for volume and tone control in televisions, mini component stereo systems, and other audio products. Their two-line serial control (I 2 C BUS) enables them to control volume and tone on the basis of signals from a microcomputer, etc. ! !! ! Applications Televisions, [Video equipped television], personal computer televisions, mini component stereo systems, car stereos. ! !! ! Features 1) I 2 C BUS facilitates direct serial control from a microcomputer of volume (main volume), balance (left / right), 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) Stable standard voltage supply and built-in I/O buffer mean that few attachments are needed. SSOP-A32 package designed to save space. 4) Matrix surround yields powerful sound. ! !! !
