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.
FApplications
CD radio cassettes, micro components, car stereos, tele-
visions
FFeatures
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.
