TECHNICAL NOTE

Sound Processor Series for Car Audio

Sound Processors

with Built-in 3-band Equalizer

BD3484FS, BD3485FS, BD3486FS

●Description

BD3484FS, BD3485FS, BD3486FS are sound processors built-in 3-band equalizer and subwoofer-outputs for car audio.

The Functions are stereo 4ch input selector, input-gain control, main volume, 3-band parametric equalizer, 6ch fader

volume. Moreover, “Advanced switch circuit”, that is ROHM original technology, can reduce various switching noise (ex.

No-signal, low frequency likes 20Hz & large signal inputs). “Advanced switch” makes control of microcomputer easier, and

can construct high quality car audio system.

●Feature

1) Standardizing I C BUS resistor map of BD348X-series can make almost of program on microcomputer common.

2) Standardizing pin configuration of BD348X-series can make PCB common.

3) Reduce the switching noise of Main volume, Fader volume, Bass, Middle, Treble, Loudness(BD3484FS), Super

bass(BD3485FS), Effect(BD3486FS) gain and attenuation by using advanced switch circuit.

（Possible

to control all

steps.）

4) Decrease the number of external parts by built-in 3-band equalizer filter and low-pass filter for subwoofer.

Possible to control Bass, Treble, Middle and LPF equalizer freely.

5) Built-in operational amplifier for Loudness. Possible to control gain setting. (BD3484FS)

6) Built-in operational amplifier for Super Bass function. Possible to control gain setting. (BD3485FS)

7) Built-in operational amplifier for Effect function. Possible to control gain setting. (BD3486FS)

8) It is equipped with output terminals of Subwoofer. Moreover, the stereo signal of the front and rear, too, can be

output by the I C BUS control.

9) It is possible for the bass, middle, treble to correspond to the simple loudness, too, with the gain adjustment

quantity of

±20dB

and 1 dB step gain adjustment.

10) Built-in level meter (BD3485FS), 7-band spectrum analyzer (BD3486FS) making music more visible.

11) Bi-CMOS process

12) Built-in ground isolation amplifier inputs, ideal for external stereo input.

13) Package of these LSI is SSOP-A32. Putting input-terminals together and output-terminals together can make PCB

layout easier and can makes area of PCB smaller.

14) It is possible to control by 3.3V / 5V for I C BUS and 2 wire serial controller.

●Use

It is suitable for car audio specially, audio equipment of mini Compo, micro-Compo, DVD, TV etc with all kinds.
