General Description
Key Features
The BD34700FV is a 4ch independent volume system.
Micro-step volume can reduce the switching pop noise
when volume changes, so it can achieve a high-quality
set. It is most suitable for subvolume of the multi channel
volume such as AV receivers, but is most suitable for
main volume of simple systems such as 2ch.

Power Dissipation
About the thermal design by 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 elements. 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 terminals.
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.
VEE Voltage
Ensure that no pins are at a voltage below that of the VEE pin at any time, even during transient condition.
Ground Wiring Pattern
GND pins which are digital ground(17pin) and analog ground(4,5,11,12,13,27,28,29,30,31,32,33,34pin) are not
connected inside LSI. These ground pins traces should be routed separately but connected to a single ground at the
reference point of the application board. 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. The absolute maximum rating of the Pd stated in this specification is when
the IC is mounted on a 70mm x 70mm x 1.6mm glass epoxy board. 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.
Rush 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 IC 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 Terminals
Because the input impedance of the terminal becomes 47kΩ when the signal input terminal makes a terminal open,
the plunge noise from outside sometimes becomes a problem. Please connect the no using input pin to GND. And
please open the no using output pin.

Operational Notes – continued 1
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.

13. Ceramic Capacitor
When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with
temperature and the decrease in nominal capacitance due to DC bias and others.
14. About power ON/OFF
1. At power ON/OFF, a pop sound will be generated and, therefore, use MUTE on the set.
2. When turning on power supplies, Vee and Vcc should be powered on simultaneously or Vee first; then followed
by Vcc. If the Vcc side is started up first, an excessive current may pass Vcc through Vee.
15. About function switching
When switching Input Selector, Mode selector or Input Gain, use MUTE on Volume.
16. Volume gain switching
In case of the boost of the volume when changing to the high gain which exceeds +20dB especially, the switching
pop noise sometimes becomes big. In this case, we recommend changing every 1 dB step without changing a gain at
once. Also, the pop noise sometimes can reduce by making micro-step volume switching time long, too.

confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect
product performance and reliability.
7. De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual
ambient temperature.
8. Confirm that operation temperature is within the specified range described in the product specification.
9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in
this document.
Precaution for Mounting / Circuit board design
1. When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product
performance and reliability.
2. In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the
ROHM representative in advance.
For details, please refer to ROHM Mounting specification
