Sound Processor with Built-in 3-band Equalizer  
BD37542FS  
General Description  
Key Specifications  
BD37542FS 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, LPF for subwoofer 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 the number of external components  
due to built-in 3-band equalizer filter, LPF for  
subwoofer. It is possible to control Q, GV, fO of  
3-band equalizer, fC of LPF, and GV of loudness by  
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 and mixing attenuator.  
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  
13.60 mm 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
