Sound Processor with Built-in 2-band Equalizer
BD37523FS
General Description
BD37523FS 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 5ch 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” also 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, 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, subwoofer LPF and
loudness filter. This makes it possible to freely
control Q, Gv, and fo of 2-band equalizer and fc of
LPF, and Gv of loudness by I2C BUS
A gain adjustment quantity of ±20dB with a 1db
step gain adjustment is possible for the bass,
middle, and treble.
Built-in subwoofer output terminals.
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
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.
