Audio sound processor IC  
BD3867AS  
Description  
Dimension (Units : mm)  
The BD3867AS is an audio sound processor IC for TVs  
that can reduce step-noise by adopting a volume and  
tone circuit with VCA system. An AGC circuit and matrix  
surround circuit are also incorporated. This IC can process  
all audio sound control in TV.

1) Volume and tone can be controlled directly from a micro-  
computer due to the adoption of I2C-BUS.  
2) Low distortion volume and low noise VCA can reduce step-noise.  
3) By use of an AGC circuit there is better blending of volume  
differences between input sources and an improvement in  
the audible S/N ratio.  
SDIP22  
4) Matrix surround circuit with phase shift technology.  
5) Good channel balance at any volume attenuation.  
6) Maximum volume attenuation value: -110dB (Typ.)
