BD37033FV-M
General Description
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.
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.
