Sound Processor with Built-in 3-band Equalizer

BD37541FS

General Description

Key Specifications

BD37541FS is a sound processor with built-in 3-band

equalizer for car audio. The functions are stereo input

selector (which can switch single and ground isolation

input), input-gain control, main volume, loudness, 5ch

fader volume and mixing input. Moreover, “Advanced

switch circuit”, which is an original ROHM technology,

can reduce various switching noise (ex. No-signal, low

frequency like 20Hz & large signal inputs). Also,

“Advanced switch” makes control of microcomputer

easier, and can construct a high quality car audio

system.



Power Supply Voltage Range:

7.0V to 9.5V

38mA(Typ)

Circuit Current (No signal):

Total Harmonic Distortion 1:

(FRONT,REAR)

0.001%(Typ)



Total Harmonic Distortion 2:

(SUBWOOFER)

0.002%(Typ)

2.3Vrms(Typ)

-100dB(Typ)



Maximum Input Voltage:

Cross-talk Between Selectors:

Volume Control Range:

Output Noise Voltage 1:

(FRONT,REAR)

+15 dB to -79dB

3.8µVrms(Typ)



Output Noise Voltage 2:

(SUBWOOFER)

4.8µVrms(Typ)

1.8µVrms(Typ)

-40°C to +85°C

Features



Residual Output Noise Voltage:

Operating Temperature Range:



Reduced switching noise of input gain control,

mute, main volume, fader volume, bass, middle,

treble, loudness, mixing by using advanced switch

circuit.

Package

W(Typ) x D(Typ) x H(Max)



Built-in differential input selector that can make

various combination of single-ended / differential

input.



Built-in ground isolation amplifier inputs, which is

ideal for external stereo input.

Built-in input gain controller reduces switching

noise for volume of a portable audio input.

Decreased number of external components due to

built-in 3-band equalizer filter and loudness filter. It

is possible to control Q, G_V, f_Oof 3-band equalizer

through I²C BUS control.



It is possible to adjust the gain of the bass, middle,

treble up to ±20dB with 1 dB step gain adjustment.

It is equipped with output terminals for Subwoofer.

Moreover, the stereo signal output of the front and

rear can also be chosen by the I²C BUS control.

Built-in mixing input.

Energy-saving design resulting in low-current

consumption is achieved by utilizing the Bi-CMOS

process. It has the advantage in quality over

scaling down the power heat control of the internal

regulators.

SSOP-A32

13.60mm x 7.80mm x 2.01mm



Input terminals and output terminals are organized

and separately laid out to keep the signal flow in

one direction which results in simpler and smaller

PCB layout.

It is possible to control the I²C BUS by 3.3V / 5V.

Applications

It is optimal for car audio systems. It can also be used

for audio equipment of mini Compo, micro Compo, TV,

etc.

○Product structure：Silicon monolithic integrated circuit ○This product has no designed protection against radioactive rays
