TECHNICAL NOTE
Sound Processor Series for Car Audios
Sound processors with
built-in 2-band Equalizer
BD3481FS, BD3482FS
●Description
BD3481FS/BD3482FS are sound processor having in it the stereo 4ch input selector, gain amplifier, stereo primary volume,
4ch fader volume, 2-band equalizer. There is no need for any particular microcomputer control In order to reduce
various shock sounds of switching. Therefore, work to develop software can be reduced drastically.
●Features
1. Reduce the shock sounds of switching of Primary / Fader Volume attenuation and Tone by using advanst switching
circuit.
2. Taking in a filter of bass and treble inside can reduce the external parts.
3. Bi-CMOS process
4. Reduce the noise of through mode by using tone-pass route.
5. Built-in ground isolation amplifier input, suited for external stereo input.
6. The package of this IC is SSOP-A20/SSOP-A24. It gathers a sound input terminals, sound output terminals
respectively and it arranges them, to be arranging facilitates the laying-out of PCB pattern and reduces PCB area
to one-way in the flow of the signal.
●Use
Best suited for car audio, and can be used for other audio units including TV, mini compo and micro compo.
