Sound Processor with Built-in 2-band Equalizer  
BD37514FS  
General Description  
Key Specifications  
BD37514FS is a sound processor with built-in 2-band  
equalizer for car audio. The functions are 4ch stereo  
input selector, input-gain control, main volume,  
loudness, and 5ch fader volume. Moreover, its  
“Advanced switch circuit”, which is an original ROHM  
technology, can reduce various switching noise (ex.  
No-signal, low frequency like 20Hz & large signal  
inputs). “Advanced switch” makes control of  
microcomputer easier, supporting the construction of a  
high quality car audio system.  
Power Supply Voltage Range:  
7.0V to 9.5V  
38mA(Typ)  
Circuit Current (No Signal):

-40°C to +85°C  
Features  
Residual Output Noise Voltage:  
Operating Temperature Range:  
Reduce switching noise of input gain control, mute,  
main volume, fader volume, bass, treble, loudness  
by using advanced switch circuit.  
Built-in

differential input selector and  
3
Package  
W(Typ) x D(Typ) x H(Max)  
single-ended input selectors  
Built-in ground isolation amplifier inputs, ideal for  
external stereo input.  
Built-in input gain controller reduces switching  
noise for volume of a portable audio input.  
Decrease the number of external components due  
to built-in 2-band equalizer filter and loudness filter.  
Also, it is possible to control Q, Gv, fo of 2-band  
equalizer, and Gv of loudness using I2C BUS  
control.  
It is possible to adjust the gain of the bass and  
treble up to ±20dB with 1 dB step gain adjustment.  
It is equipped with output terminals of Subwoofer.  
Energy-saving design resulting in low current  
consumption, by utilizing the Bi-CMOS process. It  
has the advantage in quality over scaling down the  
power heat control of the internal regulators.  
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.  
SSOP-A20  
8.70mm x 7.80mm x 2.01mm  
Applications  
It is optimal for use in car audio systems. It can also be  
used for audio equipment of mini Compo, micro Compo,  
TV, etc.  
It is possible to control the I2C BUS by 3.3V / 5V.  
○Product structure：Silicon monolithic integrated circuit ○This product has no designed protection against radioactive rays
