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.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)

S The input impedance is 47kΩ.
S A buffer if R and C1 are not present.
S The gain can be set by R and the 20kΩ.
GVC = (R ) 20kΩ) / R
Note: Set C2 (input coupling) and C1 (used to set the
gain) depending on the frequency band used.
S A band-pass filter is constructed using a multiple-feedback type active filter.
f0 can be changed using the C valve.
