6ch Electronic Volume for 5.1ch Car Theater
BD3433K
General Description
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.
 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.
