Analog Sound Processor Series
6ch Sound Processor for High-Quality Audio
with Built-in Advanced Switch
BD34602FS-M
Description
BD34602FS-M is a 6ch independent volume system. It
is designed to have high-quality sound by improving the
op-amp and optimizing the design layout. In addition, it
is compatible, same package and it has common control
with BD3461FS, therefore replacement from BD3461FS
is easy.
Features
AEC-Q100 Qualified(Note 1)
Advanced switch circuit can reduce the switching pop
noise during volume attenuation
Built-in 6ch independent volume circuit available with
changing by 1dB/Step
Built-in DIFF amplifier inputs, ideal for external input
Built-in volume circuit for mixing external signal
available with changing by 1dB/Step
Package is SSOP-A24. Putting input-terminals
together and output-terminals together can make
PCB layout easier and can makes area of PCB
smaller.
It is possible to control by 3.3V for I2C-BUS
Controller
(Note1 : Grade 3)
Applications
Suitable for the Car Audio systems, Car Navigation
systems.

(Note 1) SSOP-A24:Derating at 8.0mW/°C for operating above Ta25°C (mounted on 70×70×1.6mm ROHM standard board)
(Note 2) If it is within the operating voltage range, circuit functions and operation are guaranteed within this operating temperature.
Caution:
Operating the IC over the absolute maximum ratings may damage the IC. The damage can
either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore,
it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated
over the absolute maximum ratings.
