Sound Processor with Built-in 2-band Equalizer
BD37522FS
General Description
BD37522FS is a sound processor with built-in 2-band
equalizer for car audio. Other features are stereo 5ch input
selector, input-gain control, main volume, loudness and a
4ch fader volume. It is equipped with an “Advanced switch
circuit”, which is an original ROHM technology, that reduces
various switching noise (ex. No-signal, low frequency like
20Hz & large signal inputs).The “Advanced switch” makes
controlling of microcomputer easier and can be used for
designing high quality car audio systems.

Features
Reduced switching noise of input gain control, mute,
main volume, fader volume, bass, treble, and
loudness by using advanced switch circuit.
Built-in 1 differential input selector and 4
single-ended input selectors
Built-in ground isolation amplifier inputs which is
ideal for external stereo input.
Built-in input gain controller which reduces switching
noise for volume of a portable audio input.
Lesser number of external components due to
built-in 2-band equalizer filter and loudness filter.
These make it possible to control Q, Gv, fo of 2-band
equalizer, and Gv of loudness by I2C BUS
A gain adjustment quantity of ±20dB with a 1 dB step
gain adjustment is possible for the bass, middle, and
treble.
Energy-saving design resulting in low current
consumption is achieved by utilizing the BiCMOS
process. It has the advantage in quality over scaling
down the power heat control of the internal
regulators.
Input pins and output pins are organized and
separately laid out to keep the signal flow in one
direction which consequently, simplify pattern layout
of the set board and decrease the board dimensions.
It is possible to be controlled by a 3.3V / 5V I2C BUS

Applications
It is optimal for car audio systems. It can also be used
for audio equipment like mini Compo, micro Compo,
TV etc.
