Audio sound processor with

BH3868BFS

BH3868BFS is a Audio sound processor IC developed for TV. This IC is built-in volume, balance, tone, surround, BBE

processor and AGC. This IC can be easily controlled by tow-wire serial control (I²C BUS).

∗ BBE is a registered trade mark of BBE Sound Inc.

Note : I²C BUS is a registered trade mark of Philips.

ꢀApplications

Suitable for TV, TV-radio, PC-TV, mini-component and car audio system, etc.

ꢀFeatures

1) Volume (main volume), balance (right/left), tone (bass and treble), surround (mode and effect), BBE processor (effect)

can be controlled by I²C-BUS.

2) Volume is VCA with low distortion rate and low noise and can restrain the step noise.

3) The reference voltage source is stable, only a few external devices are required because I/O buffer is contained, and

the package is suitable for space-saving design for SSOP-A32.

4) Sound spread can be controlled by the matrix surround and effect adjustment.

5) The built-in AGC circuit can absorb the volume difference between input sources.

6) The contained BBE processor, which reproduce an original sound, controls the effect.
