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.
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.
