BH3878KS2

Features:

1) All in one chip IC incorporating functions of volume, tone,    and spectrum analyzer.
2) Soft switching that can reduce the stepping switching noise  when volume, mode selector, surround, dynamic   bass   and   the gain of graphic equalizer are switched.
3) 5-channel input selector, mode selector, volume, surround   graphic equalizer, dynamic bass, and spectrum   analyzer   can be controlled by serial control from micro controller.
4) Built-in matrix surround, B.P.F for spectrum analyzer.
5) Low distortion, low noise by BiCMOS process using   resistance ladder type volume.
6) Mode of dynamic bass and bi-amplifier can be switched.


Application

Mini component stereo, micro component stereo, CD radio cassette player, TV
