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.
