Serial sound control IC

BH3854AS / BH3854AFS

The BH3854AS and BH3854AFS are signal processing ICs designed for volume and tone control in CD radio cassettes

and other audio products. Their three-line serial control enables them to control volume and tone on the basis of signals

from a microcomputer, etc.

FApplications

CD radio cassettes, mini component stereo systems, car

stereos

FFeatures

1) They facilitate direct serial control from a microcom-

puter of volume (main volume) and tone (bass,

treble). DC control is also possible.

5) Open collector has four outputs, which makes logic

control possible.

6) Excellent for volume and tone control devices in CD

radio cassettes, micro components, car stereos,

televisions, etc.

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

VCA. Designed to minimize step noise.

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

trix surround yields powerful sound.

7) Digital GND pin and analog GND pin are separated

with an impedence of more than 1MΩ.

4) Stable standard voltage supply and built-in I / O buff-

er mean that few attachments are needed. SSOP32

package designed to save space.

FAbsolute maximum ratings (Ta = 25_C)

FRecommended operating conditions (Ta = 25_C)
