General-Purpose 6ch Electronic Volume

with Built-in Advanced Switch

BD3461FS

General Description

Key Specifications

BD3461FS is a 6ch 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, BD3461FS has a

volume switching shock sound prevention technique

called “Advanced Switch,” supporting the construction

of high quality car audio space by simple control.



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/Sub output

Lch/Rch independently.



Built-in 3ch ATT for external sound mixing that can

be controlled independently.

Built-in buffered ground isolation amplifier inputs,

ideal for external input.

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 internal regulators.

Arranges all I/O terminals together for easier PCB

layout and smaller PCB area.

10.00mm x 7.80mm x 2.10mm



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.
