BD3867AS
00W167A
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

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.
4) Matrix surround circuit with phase shift technology.
5) Good channel balance at any volume attenuation.
6) Maximum volume attenuation value: -110dB (Typ.)
