Analog Sound Processor series

Sound Processor with Built-in

Surround Sound Function

BD3491FS

General Description

Key Specification

Built in stereo 6 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 BassBoost,

Output gain, Surround by external components.

ꢀ Current upon no signal:

ꢀ TotalHarmonic Distortion:

ꢀ Maximum Input Voltage:

ꢀ Crosstalk between Selectors:

ꢀ Volume Control Range:

ꢀ Output Noise Voltage:

7mA(typ)

0.002%(typ)

2.4Vrms(typ)

100dB(typ)

0dB to -87dB

5µVrms(typ)

-40℃ to +85℃

ꢀ Residual Output Noise Voltage:

ꢀ Operating Temperature Range:

Features

ꢀ Equipped with 6 single ended stereo input

selectors

ꢀ Built-in input gain controller suitable for mobile audio.

ꢀ Volume input terminal can be used as a microphone

input terminal since its impedance remains constant

even if volume setting is changed.

Package

SSOP-A32

W(typ) x D(typ) x H(max)

13.60mm x 7.80mm x 2.01mm

ꢀ Bi-CMOS process is suitable for the design of low

current and low energy. It also provides more quality

for Bi-CMOS small scale regulator and heat in a set.

ꢀ The package of this IC is SSOP-A32. Sound input

terminals and output terminals arrangement is

optimized for easy and fast layout of PCB pattern. At

the same time, it minimizes PCB area.

Applications

ꢀ Suitable for mini-components or micro components.

Used for audio equipment of TV, DVD, etc.
