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 data 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 I2C BUS 80 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. 2About 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 x 2 Tsoft,MUTE Tsoft,MUTE MUTE advanced switching time Advanced switching time MUTE ON time 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. www.rohm.com (c) 2013 ROHM Co., Ltd. All rights reserved.

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 2.2k) to Mute terminal in series, if voltage is supplied to mute terminal in case. (Please refer Application Circuit Diagram.) 4. About Hi-Voltage function About Logic of Hi-Voltage function is follow as. Hi-Voltage ON/OFF Hivoltage ON/OFF(Select Address 01hex, D2) Level Shift(Select Address 01hex, D3) Level of amplification in the output-unit Bias-voltage in the output-unit 0 0 0 4.15 0 1 3 4.15 1 0 6 6 1 1 6 6 [dB] [V] Hi-Voltage ON Though the level of amplification in the output-unit is controlled with Level Shift (Select Address 01hex, D3), it becomes a +6dB fixation under the condition of Hi-Voltage function is ON. 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) www.rohm.com (c) 2013 ROHM Co., Ltd. All rights reserved.
