Sound Processor with Built-in 2-band Equalizer
BD37511FS
General Description
BD37511FS is a sound processor with built-in 2-band
equalizer for car audio. The functions are 3ch stereo
input selector, input-gain control, main volume and 4ch
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.

Features
Reduce switching noise of mute, main volume,
fader volume, bass, trebles by using advanced
switch circuit
Built-in 3 single-ended input selectors
Decrease the number of external components due
to built-in 2-band equalizer filter.
It is possible to adjust the gain of the bass and
treble up to ±20dB with 1 dB step gain adjustment.
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.
It is possible to control the I2C BUS by 3.3V / 5V.

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.
