Audio ICs
High-definition sound processor
BA3884F / BA3884S
The BA3884F and BA3884S are sound processor ICs that perform 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
Component stereo systems, radio cassette players, car
stereo systems, televisions, VCRs, multimedia PCs,
computer game machines and karaoke machines.
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 adjusted with the DC control in or-
der to maintain a good balance with the dynamically
changing upper frequencies.
