SSOP-A24:Derating at 8.0mW/°C for operating above Ta≥25°C (mounted on 70×70×1.6mm ROHM standard board)
If it is within the operating voltage range, circuit functions and operation are guaranteed within this operating temperature.
Operating the IC over the absolute maximum ratings may damage the IC. The damage can
either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore,
it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated
over the absolute maximum ratings.

In case of different settings, there is possibility of cause unintended behavior.
Instructions of the data format
1.
In function changing of the hatching part, it works Advanced switch(In detail, please refer p13).
2.
Upon continuous data transfer, the Select Address is circulated by the automatic increment function, as shown
below(hex).

About advanced switch circuit
【1】Advanced switch technology
1-1. Advanced switch effects
Advanced switch technology is Rohm original switching pop noise prevention technology. The audible signal is
discontinuous during the gain switching instantly which cause the noise to occur. This Advanced switch circuit will prevent
this discontinuous signal by completing the signal waveform and will significantly reduce the noise.
Figure 16. Advanced switch wave
This Advanced switch technology will start the switching when received the signal sent from the micon.
At any constant time, the switching waveform is shown as above figure. This IC will optimally operate by internally
processing the data sent from the micon to prevent the switching shock.
However, sometimes the switching waveform is not like the intended form depends on the transmission timing.
Therefore, below is the example of the relationship between the transmission timing and actual switching time. Please
consider this relationship for the setting.
1-2. The kind of the Transferring Data
・Data setting other than Advanced switch supported items
( P.9 Select Address and data Data format without hatching)
There is no particular rule about transferring data.
・Advanced switch supported items data setting
(P.9 Select Address and data Data format with hatching)
There is no particular rule about transferring data, but Advanced switch must follow the switching sequence as
mentioned in【2】.
※
Advanced switch supported blocks are “Volume” and ”EXT ON/OFF”(In detail, please refer p9).

【2】Data transmission of Advanced switch supported items
2-1. Switching time of Advanced switch
Switching time includes [Twait(Wait time)], [Tsft(A→B switching time)] and [Tsft(B→A switching time)].
25msec is needed per 1 switching. (Tsoft = Twait + 2 * Tsft, Twait=2.3msec, Tsft=11.2msec)

Figure 17. About Advanced switching time
In Figure 8, Start/Stop state is expressed as “A” and temporary state is expressed as “B”.
The switching sequence of Advance switch will be, A(start)→B→A(stop), thus switching will not stop at B state.
In other words, switching is performed from A(Initial gain)→B(set gain→A(set gain) when switching from initial gain to set
gain.
It is possible to change the switching time of Advanced switch time by setting the EXT Advanced switch multi sel and
Advanced Switch Time of EXT at select Address2.
If only EXT ON/OFF is performed in all Advanced switch operation, the switching time of Advanced switch is determined
by EXT Advanced switch multi sel and Advanced Switch Time of EXT.
For example
EXT Advanced switch multi sel is set to x8 and Advanced Switch Time of EXT is set to 14.4msec
In this case, the switching time of Advanced switch is determined as below.
EXT Advanced switch multi sel
This is equal to switching time of
x Advanced Switch Time of EXT
= 115.2msec
A→B or B→A(Tsft).
As mentioned in Figure 11 (Start sequence of Advanced switch), each ch(6channels) volume and EXT ON/OFF switch at
the same timing. When each ch(6channels) volume switches at the same time EXT ON/OFF operation is performed,
switching time of each ch(6channels) volume will be the same as EXT ON/OFF switching set by calculation above. In other
words, switching time of EXT ON/OFF has higher priority than that of the 6channels volume
Even if switching time of EXT ON/OFF is set by calculation above, when EXT ON/OFF switching is not being performed,
switching time of each ch(6channels) volume is determined as Tsft＝11.2msec. Please exercise caution when setting the
switching time of Advanced switch.

About data transmission to multi-channels, there is a caution. It is possible that Lch and Rch in same block(Front/Rear/Sub)
can be switched at the same timing. For example, when the data transmission is set as the figure below, it is possible that
OUTF1 and OUTF2 can be switched at the same timing(Data is sent for FL (Lch) and data is sent for FR (Rch)).
Please take note that Twait is wait time for starting switching and designed to 2.3msec. (Considering fluctuation of element,
Twait may change from 1.2msec (Min.) to 4.6msec (Max.).

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. 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.
Ground Voltage
Ensure that no pins are at a voltage below that of the ground 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 Terminals
Because the input impedance of the terminal becomes 100kΩ when the signal input terminal makes a terminal open,
the plunge noise from outside sometimes becomes a problem.
About unused input pin, please connect to GND through capacitor, or please set that channel MUTE.
About unused output pin, it is no problem to set to open.

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 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.
Figure 23. Example of monolithic IC structure
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
At power ON/OFF, a pop sound will be generated and, therefore, use MUTE on the set.
15. About EXT ATT(Select Address 33, 34, 35(hex)) switching
When switching EXT ATT, please set EXT OFF.
16. About Volume gain switching, EXT ON/OFF switching
In case of the boost of the volume when changing to the high gain which exceeds +12dB especially, the switching
pop noise sometimes becomes big. (For example, in case gain of the power amplifier is set to +26dB, and switching
time is set to 11.2msec)
In this case, countermeasures as below are recommended to decrease this pop noise.
・Switching gain by only 1dB/Step
・Increase switching time (In detail, please refer p9.)

residue after soldering
[h] Use of the Products in places subject to dew condensation
4.
The Products are not subject to radiation-proof design.
5.
Please verify and confirm characteristics of the final or mounted products in using the Products.
6.
In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied,
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 depending on ambient temperature. When used in sealed area, confirm that it is the use in
the range that does not exceed the maximum junction 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 on a surface-mount products, the flow soldering method must
be used on a through hole mount products. If the flow soldering method is preferred on a surface-mount products,
please consult with the ROHM representative in advance.
For details, please refer to ROHM Mounting specification
