Sound Processor Series for Car Audio

Sound Processors with Built-in

3-band Equalizer

BD37531FV,BD37532FV,BD37533FV,BD37534FV

No.10085EAT06

●Description

BD37531FV, BD37532FV, BD37533FV, BD37534FV are sound processors built-in 3-band equalizer for car audio. The

functions are stereo input selector available to switch single end input and ground isolation input, input-gain control, main

volume, loudness, 5ch fader volume, LPF for subwoofer(except BD37531FV), mixing input(except BD37531FV,

BD37532FV). 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.

●Features

1) Reduce switching noise of input gain control, mute, main volume, fader volume, bass, middle, treble, loudness

by using advanced switch circuit [Possible to control all steps]

2) Built-in differential input selector that can make various combination of single-ended / differential input.

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

4) Built-in input gain controller reduces switching noise for volume of a portable audio input.

5) Decrease the number of external components by built-in 3-band equalizer filter, LPF for subwoofer (except BD37531FV),

loudness filter. And, possible to control Q, Gv, fo of 3-band equalizer and fc of LPF, Gv of loudness by I²C BUS control

freely

6) It is possible for the bass, middle, treble to the gain adjustment quantity of ±20dB and 1 dB step gain adjustment.

7) Terminals for the subwoofer outputs are equipped, and the audio signal outputs of front, back and subwoofer can be

chosen with the I2C BUS control.

8) Built-in mixing input, mixing attenuator. (except BD37531FV, BD37532FV)

9) Bi-CMOS process is suitable for the design of low current and low energy. And it provides more quality for small

scale regulator and heat in a set.

10) Package is SSOP-B28. Putting input-terminals together and output-terminals together can make PCB layout easier and

can makes area of PCB smaller.

11) It is possible to control by 3.3V / 5V for I²C BUS.

●Applications

It is the optimal for the car audio. Besides, it is possible to use for the audio equipment of mini Compo, micro Compo, TV

etc with all kinds.
