General-Purpose 4ch Electronic Volume
with Built-in Advanced Switch
BD3464FV
General Description
BD3464FV is a 4ch electronic volume which has the
best audio efficiency in the industry. It 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.
 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.
