BA3888S

The BA3888S is a sound processor IC that performs phase and harmonic compensation on audio signals to accurately

reproduce the “rise” section of audio signals that determines the characteristics of the sound, and thus reproduce the

original recording as naturally as possible.

FApplications

VCRs, tape recorders and video equipped television

FFeatures

1) Corrects distortion in the rising section of audio sig-

nals that results from miss-matched speakers and

amplifiers, and reproduces the original sound faith-

fully.

2) To allow application with all types of speakers and

sources, the clarity can be adjusted using DC control.

3) DC control provided for selection of either processor

mode or bypass mode.

4) Bass boost can be set in the range 0dB to 9dB (Typ.)

using external components.

5) A noise gate circuit naturally cuts hiss at low volume.

FAbsolute maximum ratings (Ta = 25_C)
