6ch Electronic Volume for 5.1ch Car Theater

BD3433K

General Description

Key Specifications

BD3433K is a 6ch electronic volume device for 5.1ch

Car Theater. It incorporates various functions such as

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 also provides high performance functions to

achieve low distortion, low noise and a high voltage

output of 5.6Vrms. QFP44 package which offers

savings in space and components is used to be suited

for applications such as car audio and car navigation.

Features



High output voltage of 5.6Vrms is achievable

Provided with 2 lines of outputs to the built-in

power amp and the pre-out.



Reduces volume switching noise by installing

the advanced 6ch independently-controlled

electronic volume with soft switching.

QFP44

14.00mm x 14.00mm x 2.25mm



High performance capabilities such as low

distortion rate (0.001%), low noise (3µVrms)

Different signals from different sources can be

outputted to the front and rear sections

independently and this provides an option of

rear-seat entertainment.



Incorporates monophonic differential input circuit

suited for inputting navigation voice and telephone

speech.

These monophonic voices can be mixed with the

front output signals.



Energy-saving design resulting in low current

consumption, by utilizing the Bi-CMOS process.

It has the advantage in quality over scaling down

the power heat control of the internal regulators.

3-wire serial interface supported for both of 3.3V

and 5V microcomputers.

Applications

For car audio equipment, car navigation equipment,

and hybrid systems.

○Product structure：Silicon monolithic integrated circuit ○This product has no designed protection against radioactive rays
