Notes on data format
1. “Advanced switch” function is available for the hatched parts on the above table.
2. In case of transferring data continuously, Select Address(hex) flows by Automatic increment function, as shown
below.
→01→02→05→06→28→29→2A→2B→2C→2D→30
3. Input selector that is not corresponded for “Advanced switch” function, cannot reduce the noise caused when
changing the input selector. Therefore, it is recommended to turn on mute when changing these settings.
4. In case of setting to infinite “-∞” by using Fader when input selector setting is changed, please consider “Advanced
switch” time.

This IC will become active-state by sending data of Select Address 01(hex) on I C-bus after 20msec from that VCC1 and
VCC2 reaches over 7.0V. Therefore, this command must always send in start-up sequence. In addition, External MUTE
means recommended period that the muting outside IC.

About Advanced Switch Circuit
【1】Advanced switch technology
1-1. Advanced switch effects
Advanced switch technology is ROHM original technology that can prevent from switching pop noise. If changing the
gain setting (for example Fader) immediately, the audible signal will become discontinuously and pop noise will be
occurred. This Advanced switch technology will prevent this discontinuous signal by completing the signal waveform
and will significantly reduce the noise.

If the gain instantly changes after the data is transmitted, the DC
fluctuation will occur as much as before and after the oscillation
different. This technology makes this fluctuation changes slow.

waveform
Figure 17. The explanation of advanced switch waveform
This Advanced switch circuit will start operating when the data is transmitted from microcontroller.
Advanced switch waveform is shown as the figure above. For preventing switching noise, this IC will operate
optimally by internal processing after the data is transmitted from microcontroller.
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 that is not corresponded to Advanced switch
(Page11 Select Address & Data Data format without hatching)
There is no particular rule about transferring data.
・Data setting that is corresponded to Advanced switch
(Page11 Select Address & 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】as follows.

【2】Data transmission that is corresponded to Advanced switch
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)

Advanced Switch Time (tSOFT)
In the figure above, Start/Stop state is expressed as “A” and temporary state is expressed as “B”.
The switching sequence of Advanced switch consists of the cycle “A(start)→B(temporary)→A(stop)”. Therefore, switching
sequence will not stop at B state.
For example, switching is performed from A(Initial gain)→B(set gain)→A(set gain) when switching from initial gain to set
gain. And switching time (tSFT) of A→B or B→A are equal.
2-2. About the data transmission’s timing in same block state and switching operation
■ Transmitting example 1
This is an example when transmitting data in same block with “enough interval for data transmission”.
(enough interval for data transmission : 1.4 x tSOFT * ”1.4” includes tolerance margin.)
Definition of example expression :
F1=Fader 1ch Front, F2=Fader 2ch Front, R1=Fader 1ch Rear, R2=Fader 2ch Rear

■ Transmitting example 2
This is an example when the transmission interval is not enough (smaller than “Transmission example 1”). When
the data is transmitted during first switching operation, the second data will be reflected after the first switching
operation. In this case, there is no wait time (tWAIT) before the second switching operation.

transmission interval than “Transmission example 3”.
IC has internal data-storage buffer and buffer transmitted data as storage data constantly.
However, only the latest data is kept so, in this example, +4dB data transmitted secondly is ignored.

■ Transmitting example 1
About the transmission to several blocks also, as explained in the previous section, though there is no restriction of the
2
I C-bus data transmitting timing, the start timing of switching follows the figure of previous page, the order of advanced
switch start.
Therefore, it isn't based on the data transmitting order, and an actual switching order becomes as the figure of previous
page, “The order of advanced switch start”.
Each block data is being transmitted separately in the transmitting example 1, but it becomes the same result even if data
are transmitted by automatic increment.

Thermal Derating Curve
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.

Application Information
1.
Absolute maximum rating voltage
When voltage is impressed to VCC exceeding absolute maximum rating voltage, circuit current increases rapidly
and it may result in property degradation and destruction of a device.
When impressed by a VCC terminal (21,26pin) especially by serge examination etc., even if it includes an of
operation voltage +serge pulse component, be careful not to impress voltage (about 14V VCC terminal) much higher
than absolute maximum rating voltage.
2.
About a signal input part
In the signal input terminal, the value of the input coupling capacitor C(F) should be sufficient

About TEST1,2 terminal(19,20pin)
About TEST1,2 terminal(19,20pin), please use with OPEN.
5.
About signal input terminals
Because the inner impedance of the terminal becomes 100 kΩ or 250 kΩ when the signal input terminal makes a
terminal open, the plunge noise from outside sometimes becomes a problem. When there is an unused signal input
terminal, design so it is shorted to ground.
6.
About changing gain of Input Gain and Fader Volume
In case of the boost of the input gain and fader volume when changing to the high gain which exceeds
20 dB 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 advanced switch time long, too.

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.
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 maximum junction temperature 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 maximum junction temperature 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.

Operational Notes – continued
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. 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.
