Sound control IC

BH3852S / BH3852FS

The BH3852S and BH3852FS are signal processing ICs designed for volume and tone control in CD radio cassettes
and other audio products. They can be used without a microcomputer because they use DC current for control.

Applications

CD radio cassettes, micro components, car stereos, tele-
visions

Features

1) Can control volume (main volume) and tone (bass,

treble).

2) Volume is produced by a low-distortion, low-noise

VCA, is controlled with DC current, and, due to an in-
ternal reference voltage with temperature com-
pensation, can control two channels with a single
variable resistor.

3) Input amp can be used for gain adjustment, and ma-

trix surround yields powerful sound.
