Sound Processor with Built-in 3-band Equalizer
BD37533FV
General Description
BD37533FV is a sound processor with built-in 3-band
equalizer for car audio. A stereo input selector is
available that functions to switch single end input and
ground isolation input, input-gain control, main volume,
loudness, 5ch fader volume, LPF for subwoofer and
mixing input. Moreover, “Advanced switch circuit”,
which is an original ROHM technology, can reduce
various switching noise (ex. No-signal, low frequency
like 20Hz & large signal inputs). Also, “Advanced
switch” makes microcomputer control easier, and
constructs a high quality car audio system.
Features
Reduced switching noise of input gain control,
mute, main volume, fader volume, bass, middle,
treble, loudness by using advanced switch circuit
Built-in differential input selector that can make
various combination of single-ended / differential
input.
Built-in ground isolation amplifier inputs, which is
ideal for external stereo input.
Built-in input gain controller reduces volume
switching noise of a portable audio input.
Decreased number of external components due to
built-in 3-band equalizer filter, LPF for subwoofer
and loudness filter. It is possible to freely control
the Q, Gv, fo of the 3-band equalizer, fc of the
LPFand Gv of loudness by I2C BUS control.
A gain adjustment quantity of ±20dB with a 1 dB
step gain adjustment is possible for the bass,
middle and treble.
Equipped with terminals for the subwoofer outputs.
Also, the audio signal outputs of the front, rear and
subwoofer can be chosen using the I2C BUS
control.
Built-in mixing input, mixing attenuator.
Energy-saving design resulting in low current
consumption is achieved 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 control I2C BUS with 3.3V / 5V
