Sound Processor IC
BH3878KS2
Description BH3878KS2 is a sound controller IC for mini component stereo. 5-channel input selector, vocal fader, volume, surround, 5-band graphic equalizer, dynamic bass, and 5-band spectrum analyzer are all integrated into this single chip. Switching noise is reduced when volume, vocal fader, surround and dynamic bass are changed by soft switch. 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. Applications Mini component stereo, micro component stereo, CD radio cassette player, TV Absolute Maximum Ratings (Ta=25C)
