Sound Processors for Car Audios General-Purpose Electronic Volume with Built-in Advanced Switch No.11085EBT09 BD3460FS,BD3461FS,BD3464FV,BD3465FV Description BD3460FS, BD3461FS, BD3464FV, BD3465FV is 4ch / 6ch electronic volume which has audio efficiency of the industry best level. It has Outside sound mixing function (with volume)(BD3461FS, BD3465FV) in favorite channel to mixing of the portable telephone and car navigation's guide sound. Also, which has Ground isolation amplifier(BD3460FS, BD3461FS) when connecting with the outside voice inputs such as portable audio and car navigation. It is lineup and possible to be chosen to the use by it. Also, Rohm has the volume switching shock sound prevention technique "Advanced switch". Therefore, it supports the construct of the high quality car audio space by the simple control. Features 1) Reduce switching noise of volume by using advanced switch circuit. (Possible to control all steps) 2) Low distortion (0.0004% typ), Low noise (1.6Vrms) 3) Mixing for external sound monaural 3ch. It is possible that is mixed to front/Rear/Sub output (BD3461FS) Front/Rear output (BD3465FV) Lch/Rch independently. 4) Built-in 3ch ATT for external sound mixing that can be controlled independently. (BD3461FS, BD3465FV) 5) Built-in buffered stereo ground isolation amplifier inputs, ideal for external input. (BD3460FS, BD3461FS) 6) Bi-CMOS process is suitable for the design of low current and low energy. And it provides more quality for small scale regulator and heat in a set. 7) Package is SSOP-A24,SSOP-B20. Putting input-terminals together and output-terminals together can make PCB layout easier and can makes area of PCB smaller. 2 8) It is possible to control by 3.3V / 5V for I C BUS. Applications It is the optimal for the car audio. Besides, it is possible to use for the car navigation, audio equipment of mini Compo, micro Compo, DVD, TV etc with all kinds.

But Advanced switch order follows the following 2. 2Transferring data of the Advanced switch 2-1. The timing chart from the transferring data timing to the Advanced switch start timing is as follows. Transferring data example 1 It is the same even if it transfers data in auto increment mode. There are no timing regulations of I2C BUS transferring data. But the timing of a change start after the end of the present change. In addition, the timing of Advanced switch is not depended of a transferring data turn, but conforms in turn of the following figure.

The following phenomenon may occur. 1. Volume (Fader) gain does not change. 2. Volume (Fader) gain changes to MUTE. Therefore, the transferring data from a microcomputer should send to conform to the following conditions. When the Volume (Fader) change data send, please send the same data twice as below.

If you intend to use our Products under any special or extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of product performance, reliability, etc, prior to use, must be necessary: [a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents [b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust [c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2 [d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves [e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items [f] Sealing or coating our Products with resin or other coating materials [g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning 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 (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 Notice - GE (c) 2014 ROHM Co., Ltd. All rights reserved. Rev.002 Datasheet Precautions Regarding Application Examples and External Circuits 1. If change is made to the constant of an external circuit, please allow a sufficient margin considering variations of the characteristics of the Products and external components, including transient characteristics, as well as static characteristics. 2. You agree that application notes, reference designs, and associated data and information contained in this document are presented only as guidance for Products use. Therefore, in case you use such information, you are solely responsible for it and you must exercise your own independent verification and judgment in the use of such information contained in this document. ROHM shall not be in any way responsible or liable for any damages, expenses or losses incurred by you or third parties arising from the use of such information. Precaution for Electrostatic This Product is electrostatic sensitive product, which may be damaged due to electrostatic discharge. Please take proper caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be applied to Products. Please take special care under dry condition (e.g. Grounding of human body / equipment / solder iron, isolation from charged objects, setting of Ionizer, friction prevention and temperature / humidity control). Precaution for Storage / Transportation 1. Product performance and soldered connections may deteriorate if the Products are stored in the places where: [a] the Products are exposed to sea winds or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2 [b] the temperature or humidity exceeds those recommended by ROHM [c] the Products are exposed to direct sunshine or condensation [d] the Products are exposed to high Electrostatic 2. Even under ROHM recommended storage condition, solderability of products out of recommended storage time period may be degraded. It is strongly recommended to confirm solderability before using Products of which storage time is exceeding the recommended storage time period. 3. Store / transport cartons in the correct direction, which is indicated on a carton with a symbol. Otherwise bent leads may occur due to excessive stress applied when dropping of a carton. 4. Use Products within the specified time after opening a humidity barrier bag. Baking is required before using Products of which storage time is exceeding the recommended storage time period. Precaution for Product Label QR code printed on ROHM Products label is for ROHM's internal use only. Precaution for Disposition When disposing Products please dispose them properly using an authorized industry waste company. Precaution for Foreign Exchange and Foreign Trade act Since our Products might fall under controlled goods prescribed by the applicable foreign exchange and foreign trade act, please consult with ROHM representative in case of export.
