Sound Processor Series for Car Audio 6ch Electronic Volume for 5.1ch Car Theater BD3433K No.10085EAT01 ●Description The 6ch electronic volume for 5.1ch car theater is an electronic volume device incorporating 6ch input selector (front/rear independently-controlled), input gain amp (front/rear independently-controlled), 6ch independently-controlled electronic volume (capable of soft switching), 6ch output gain amp (2-line outputs), differential input for monophonic signals, electronic volume for monophonic signals (capable of soft switching), and mixing circuit for monophonic signals. It is provided with the high performance functions to achieve low distortion and low noise and, furthermore, to output the 5.6Vrms high voltage. The QFP44 package which realizes savings in space and components is used to be suited for applications such as car audio and car navigation. ●Features 1) High voltage output of 5.6Vrms achieved Provided with 2 lines of outputs to the built-in power amp and the pre-out 2) Volume switching noise is reduced by installing the advanced 6ch independently-controlled electronic volume with soft switching. 3) High performance capabilities such as low distortion rate (0.001%), low noise (3µVrms) 4) Different signals from the different sources can be outputted to the front and rear sections independently and this provides an option of rear-seat entertainment. 5) Incorporate the monophonic differential input circuit suited for inputting navigation voice and telephone speech. These monophonic voices can be mixed with the front output signals. 6) Adopting the Bi-CMOS process achieves low current consumption, which contributes to energy-saving design. It has the advantage in quality over scaling down and heat reduction of the internal regulators. 7) 3-wire serial interface supported for both of 3.3V and 5V microcomputers ●Applications For car audio equipment, car navigation equipment, and hybrid systems. www.rohm.com © 2010 ROHM Co., Ltd.
