Analog Audio Processors
Sound Processors with Built-in
Surround Sound Function
BD3490FV
●General Description
Built in stereo 4 input selectors and volume that there is
not an impedance change of a volume terminal. And this
is sound processor can realize 2-band equalizer
(bass/treble, gain±14dB / 2dB_step) and bass-boost,
output-gain, surround by external components.
●Features
Built in stereo 4 input selectors (single end).
Built-in input gain controller for volume of a portable
audio input.
When the volume setting exchanging, it can use a
volume input terminal as a microphone input terminal
because there is not an impedance change of a
volume input terminal.
Bi-CMOS process is suitable for the design of low
current and low energy. And it provides more quality
for Bi-CMOS small scale regulator and heat in a set.
The package of this IC is SSOP-B28. It gathers a
sound input terminals, sound output terminals
respectively and it arranges them, to be arranging
facilitates the laying-out of PCB pattern and reduces
PCB area to one-way in the flow of the signal.
