Analog Audio Processors series  
Sound Processors  
for Car Audio  
BD37033FV-M  
General Description  
Key Specifications  
BD37033FV-M is sound processors for car audio. The  
functions are stereo input selector with single end 3 and  
ground isolation input 2, volume, 3-band parametric  
equalizer, loudness, 6ch fader volume, LPF for  
subwoofer, anti-aliasing-filter, Mixing 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.

Features  
ꢀ Reduce switching noise of volume, mute, fader  
volume, bass, middle, treble, loudness by using  
advanced switch circuit [Possible to control all  
steps].  
ꢀ Built-in input selector (single 3 / diff 2).  
ꢀ Decrease the number of external components by  
built-in 3-band equalizer filter, LPF for subwoofer,  
loudness filter. And, possible to control Q, Gv, fo  
of 3-band equalizer and fc of LPF, Gv, fo of  
loudness by I2C BUS control freely.  
ꢀ Built-in mixing volume and anti-aliasing-filter.  
ꢀ Built-in anti-GSM-noise-filter.  
ꢀ Package is SSOP-B28. Putting input-terminals  
together and output-terminals together can make  
PCB layout easier and can makes area of PCB  
smaller.  
SSOP-B28  
ꢀ It is possible to control by 3.3V / 5V for I2C BUS.  
ꢀ AEC-Q100 Qualified.  
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.
