(*1): If “Level Meter Reset” is set as Reset(“b1), a reset pulse will be outputted only once to a level meter block.
Also about this register, after a reset pulse output returns to a Hold(“b0) state, without holding a Reset(“b1) state.
Therefore, in order to change into a Hold state, it is not necessary to carry out a register setup again.
(*2): If Subwoofer LPF fc is set as 「PASS」('b000), LPF PHASE is compulsorily fixed to 0°('b0).

Recommendation of VOLUME DIAGRAM
The example of the SET VOLUME DIAGRAM by Volume(SelectAddress 20(hex)) and Fader(SelectAddress 28,29,2A,2B,2C,
2D(hex)) is explained in the following.
Example 1 ) It is recommended when a signal level is made to attenuate, a decline by Volume is done by -24dB. It is adjusted
with Fader after -24dB. S/N ratio can improve in comparison with the case that it is made to attenuate only with Volume.

About Advanced switching circuit
【1】About Advanced switch
1-1. Effect of Advanced switch
It is the ROHM original technology for prevention of switching noise. When gain switching such as volume and tone
control is done momentarily, a music signal doesn’t continue, and unpleasant shock noise is made. Advanced switch
can reduce shock noise with the technology which signal wave shape is changed to gently so that a music signal may
not continue drastically.
select
slave

Gain is made to change right after the data transmission momentarily. At this
time, a change of DC occurs only in the one for the difference of the amplitude

before and after the change.. The technology made to make this change slow
a change of DC
Wave of Advanced switching
Advanced switch starts switching after the control data transmitted by a microcomputer are received. It takes one
fixed time, and wave shape transits as the above figure. The data transmitted by a microcomputer are processed inside,
and the most suitable movement is done inside the IC so that switching shock noise may not be made.)
But, it presumes by the transmitting timing when it doesn’t become intended switching wave shape because it is the
function which needs time. The example which relations with the switching time of the data transmitting timing and the
reality were shown in is given to it in the following. It asks for design when it is confirmed well.
About a kind of transmission method
・A data setup (by the data format, the thing which isn’t indicated by gray) except for the item for advanced switch
There is no regulation in transmission specially.
・The data setup (by the data format, the thing which gray indication is) of the item for advanced switch
Though there is no regulation in data transmission, the switching order when data are transmitted to several blocks
follows the
next 2-3.
【2】About transmission DATA of advanced switching item
2-1. About switching time of advanced switch
advanced switch ON/ OFF is set up in ON to make advanced switch function effective.
And, though it becomes the same completely, the movement time of advanced switch can set up only MUTE in the
independence.
As for these, set it up referring to select address 01(hex) of the data format.
There are transition time to be equivalent to the setup value, and treatment time (effect-less time) inside the IC in
advanced switch. Therefore, actual switching time (Tsoft and Tsoft, MUTE) is defined as follows.
The treatment time of around 1 time needs the time of 2 times of the setup value
The treatment time of around 1 time of MUTE becomes the same time as the setup value (movement time). (Example : in the case of
(movement time). (Example : in the case of 11.2msec, 22.4msec)
3.2msec, with OFF? on, each ON? off, 3.2msec
Tsoft=setup value × 2
Tsoft,MUTE
Tsoft,MUTE
MUTE advanced switching time
Advanced switching time

MUTE OFF time
Setup value 11.2msec should be recommended in switch time of advanced switch. But, when a shock noise level
during gain switching isn’t sufficient, it has the possibility that it can be reduced by setting it up more this long on the
actual use. But, be careful because an response in switching of around one time becomes slow when you lengthen
time.

The timing of the switching start follows the figure of the former page though there is no restriction of the I C BUS data

Therefore, it isn’t based on the data transmitting order, and an actual switching turn becomes the turn of the upper figure.

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.

Notes for use
1.Absolute maximum rating voltage
When it impressed the voltage on VCC more than the absolute maximum rating voltage, circuit currents increase
rapidly, and there is absolutely a case to reach characteristic deterioration and destruction of a device. In particular in a
serge examination of a set, when it is expected the impressing serge at VCC terminal (14,24pin), please do not
impress the large and over the absolute maximum rating voltage (including a operating voltage + serge ingredient
(around 14V))
2.About a signal input part
1)In the signal input terminal, the constant setting of input coupling capacitor C(F) be sufficient input impedance
RIN(Ω) inside IC and please decide. The first HPF characteristic of RC is composed.

2) SHORT mode is the command which makes switch SSH =ON an input selector part and input impedance RIN of all
terminals, and makes resistance small. Switch SSH is OFF when not choosing a SHORT command.
A constant time becomes small at the time of this command twisting to the resistance inside the capacitor
connected outside and LSI. The charge time of a capacitor becomes short. Since SHORT mode turns ON the
switch of SSH and makes it low impedance, please use it at the time of a non-signal.
3.About Mute terminal(15pin) when power supply is off
Any voltage shall not be supplied to Mute terminal (15pin) when power-supply is off.
Please insert a resistor (about 2.2kΩ) to Mute terminal in series, if voltage is supplied to mute terminal in case.
(Please refer Application Circuit Diagram.)

・Under the condition of Hi-Voltage function is OFF, 0dB/+3dB switching is possible by the setup of Level Shift.
・Under the condition of Hi-Voltage function is OFF, bias-voltage is 4.15V regardless of the setup of Level Shift.
・The use of the external MUTE on the set side is recommended because shock noise by the DC step is made when
ON/OFF switching of the Hi-Voltage function is done.
・The initial condition of Hi-Voltage function is Hi-Voltage=ON after a power supply is started)
