6ch Electronic Volume for 5.1ch Car Theater
BD3433K
General Description
BD3433K is a 6ch electronic volume device for 5.1ch
Car Theater. It incorporates various functions such as
6ch input selector (front/rear independently-controlled),
input gain amp (front/rear independently-controlled),
6ch independently-controlled electronic volume
(capable of soft switching), 6ch output gain amp (2-line
outputs), differential input for monophonic signals,
electronic volume for monophonic signals (capable of
soft switching), and mixing circuit for monophonic
signals. It also provides high performance functions to
achieve low distortion, low noise and a high voltage
output of 5.6Vrms. QFP44 package which offers
savings in space and components is used to be suited
for applications such as car audio and car navigation.
Features
High output voltage of 5.6Vrms is achievable
Provided with 2 lines of outputs to the built-in
power amp and the pre-out.
Reduces volume switching noise by installing
the advanced 6ch independently-controlled
electronic volume with soft switching.
High performance capabilities such as low
distortion rate (0.001%), low noise (3µVrms)
Different signals from different sources can be
outputted to the front and rear sections
independently and this provides an option of
rear-seat entertainment.
Incorporates monophonic differential input circuit
suited for inputting navigation voice and telephone
speech.
These monophonic voices can be mixed with the
front output signals.
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.

In changing command setting value, enable to select command from No.0 to No.15
Transmission has to be every 16bit as above format.
(3) Initial Value when Power Source is ON.
When power is ON, built-in power on reset circuit initializes setting data to bit “0” (Low) within the IC. However, just in
case of set design stage, initial data has to be sent to all addresses when turning power ON, and mute setting is
recommended during this initial data transmission.
(4) Preventive Measure for Malfunction by Electrostatic Surge
The IC’s logic circuit has shift registers to retain 16bit serial data which is external input from micon etc. The data,
which is retained by shift registers, will be synchronized with CS signal leading edge, then is latched to each
function. Therefore, if electrostatic surge is applied to the logic signal terminal (CS, SCK, SDA), inappropriate latch
may cause malfunction of internal circuit. As a preventive measure for malfunction, 0000(hex) data transmission for
command No.0 (backup area), at the end of every data transmission to specific command to initialize shift register
in the IC is recommended.

Operational Notes
1. 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.
2. 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. VEE Voltage
Ensure that no pins are at a voltage below that of the VEE pin at any time, even during transient condition.
4. 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. 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.
7. 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. Operation Under Strong Electromagnetic Field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
9. 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. 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.
11. 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.

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 VEE > Pin A and VEE > Pin B, the P-N junction operates as a parasitic diode.
When VEE > 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 VEE voltage to an input pin (and thus to the P substrate) should be
avoided.
