Audio ICs

Audio sound controller

BH3857AFV

The BH3857AFV is a signal-processing IC for controlling audio quality in CD radio-cassette players and mini-component

stereo systems. Three-line serial control is available making it easy to adjust tone and volume using a microprocessor.

FApplications

Mini-component stereo systems, CD radio cassette play-

ers, car audio systems and TVs.

FFeatures

1) Volume (main volume) and tone (bass and treble)

control possible by direct serial link to a microproces-

sor. DC control is also possible.

2) Volume control is done with a low-distortion, low-

noise VCA, and step noise is suppressed.

3) The gain of the input amplifier can be adjusted, and

two surround matrixes are available to expand the

sound.

4) The IC includes a stable reference voltage source

and input buffer to reduce external component re-

quirements, and comes in a compact 40-pin SSOP

package that is perfect for compact designs.

5) Four open-collector outputs are provided to make

logic control possible.
