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 (I2C BUS) enables them to control volume and tone on the basis of signals from a microcomputer, etc.

Features
1) I2C 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.

Applications
    Televisions, [Video equipped television], personal computer televisions, mini component stereo systems, car stereos
