BH3852S Datasheet Sound Controller

Manufacturer: ROHM

Overview: Audio ICs 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 microputer because they use DC current for control.

Also, volume curves sometimes depart from target values when there is a bination of low temperature and reduced power.

(2) Primary amp BH3852S / BH3852FS S The input impedance is 47kΩ.

Key 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 internal reference voltage with temperature compensation, can control two channels with a single variable resistor. FAbsolute maximum ratings (Ta = 25_C) 3) Input amp can be used for gain adjustment, and matrix surround yields powerful sound.
