General-Purpose 4ch Electronic Volume
with Built-in Advanced Switch
BD3465FV
General Description
BD3465FV is a 4ch electronic volume which has the
best audio efficiency in the industry. It has an external
sound mixing function (with volume) in the favorite
channel for mixing of portable audio and car
navigation’s guide sound. Also, BD3465FV has a
volume switching shock sound prevention technique
called “Advanced Switch,” supporting the construction
of high quality car audio space by simple control.
Features
 Reduce switching noise of volume by using
Advanced Switch circuit.
 Mixing for external sound monaural 3ch. It is
possible that is mixed to front/Rear output Lch/Rch
independently.
 Built-in 3ch ATT for external sound mixing that can
be controlled independently.
 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.
 Arranges all I/O terminals together for easier PCB
layout and smaller PCB area.
 I²C BUS can be controlled by 3.3V / 5V.
Applications
It is optimal for car audio. It can also be used for car
navigation, audio equipment of mini Compo, micro
Compo, DVD, TV, etc.
