Sound Processor with Built-in 2-band Equalizer
BD37513FS
General Description
Key Specifications
BD37513FS is a sound processor with built-in 2-band
equalizer for car audio. The functions are 4ch stereo
input selector, input-gain control, main volume,
loudness, 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 input gain control, mute,
main volume, fader volume, bass, treble, loudness
by using advanced switch circuit.
Built-in
1
differential input selector and
3
single-ended input selectors
Built-in ground isolation amplifier inputs, ideal for
external stereo input.
Built-in input gain controller reduces switching
noise for volume of a portable audio input.
Decrease the number of external components due
to built-in 2-band equalizer filter and loudness filter.
Also, it is possible to control Gv using I2C BUS
control.
SSOP-A20
8.70mm x 7.80mm x 2.01mm
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.
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.
It is possible to control the I2C BUS by 3.3V/5V.
○Product structure：Silicon monolithic integrated circuit ○This product has no designed protection against radioactive rays

Advanced switch
Note
1. The Advanced Switch works in the latch part while changing from one function to another.
2. Upon continuous data transfer, the Select Address rolls over because of the automatic increment function, as
shown below.
→01→02→03→05→06→20→28→29→2A→2B→2C
→41→44→47→51→54→57→75
3. For the function of Input Selector etc, Advanced Switch is not used. Therefore, please apply mute on the set side
when changing these settings.
4. When using mute function of this IC at the time of changing input selector, please switch mute ON/OFF while
waiting for advanced-mute time.

Power Dissipation
About the thermal design of the IC
Characteristics of an IC have a great deal to do with the temperature at which it is used, and exceeding absolute maximum
ratings may degrade and destroy the device. Careful consideration must be given to the heat of the IC from the two
standpoints of immediate damage and long-term reliability of operation.

Operational Notes
1.
2.
Reverse Connection of Power Supply
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when
connecting the power supply, such as mounting an external diode between the power supply and the IC’s power
supply pins.
Power Supply Lines
Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the
digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog
block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and
aging on the capacitance value when using electrolytic capacitors.
3.
4.
Ground Voltage
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.
Ground Wiring Pattern
When using both small-signal and large-current ground traces, the two ground traces should be routed separately but
connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal
ground caused by large currents. Also ensure that the ground traces of external components do not cause variations
on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance.
5.
Thermal Consideration
Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in
deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, increase the board size
and copper area to prevent exceeding the Pd rating.
6.
7.
Recommended Operating Conditions
These conditions represent a range within which the expected characteristics of the IC can be approximately obtained.
The electrical characteristics are guaranteed under the conditions of each parameter.
Inrush Current
When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow
instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power
supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and
routing of connections.
8.
9.
Operation Under Strong Electromagnetic Field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
Testing on Application Boards
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may
subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply
should always be turned off completely before connecting or removing it from the test setup during the inspection
process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during
transport and storage.
10.
11.
Inter-pin Short and Mounting Errors
Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in
damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin.
Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and
unintentional solder bridge deposited in between pins during assembly to name a few.
Unused Input Pins
Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and
extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small charge
acquired in this way is enough to produce a significant effect on the conduction through the transistor and cause
unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the power
supply or ground line.

Operational Notes – continued
12.
Regarding the Input Pin of the IC
This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them
isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a
parasitic diode or transistor. For example (refer to figure below):
When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.
When GND > Pin B, the P-N junction operates as a parasitic transistor.
Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual
interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to
operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be
avoided.

About a Signal Input Part
(a) About Input Coupling Capacitor Constant Value
In the input signal terminal, please decide the constant value of the input coupling capacitor C(F) that would be
sufficient to form an RC characterized HPF with input impedance RIN(Ω) inside the IC.

(b) About the Input Selector SHORT
SHORT mode is the command which makes switch SSH =ON of input selector part so that the input impedance
RIN of all terminals becomes small. Switch SSH is OFF when SHORT command is not selected.
The constant time brought about by the small resistance inside and the capacitor outside the LSI becomes
small when this command is used. The charge time of the capacitor becomes short. Since SHORT mode turns
ON the switch of SSH and makes it low impedance, please use it at no signal condition.
14.
15.
About Mute Terminal(Pin 11) when power supply is OFF
There should be no applied voltage across the Mute terminal (Pin 11) when power-supply is OFF.
A resistor (about 2.2kΩ) should be connected in series to Mute terminal in case a voltage is supplied to Mute terminal.
(Please refer Application Circuit Diagram.)
