TDA7344

DIGITAL CONTROLLED AUDIO PROCESSOR

WITH SURROUND SOUND MATRIX

1 STEREO INPUT

VOLUME CONTROL IN 1.25dB STEP

TREBLE AND BASS CONTROL

THREE SURROUND MODES ARE AVAIL-

ABLE:

– MOVIE, MUSIC AND SIMULATED

FOUR SPEAKER ATTENUATORS:

– 4 INDEPENDENT SPEAKERS CONTROL

IN 1.25dB STEPS FOR BALANCE FACILITY

– INDEPENDENT MUTE FUNCTION

ALL FUNCTIONS PROGRAMMABLE VIA SE-

RIAL BUS

DESCRIPTION

The TDA7344 is a volume tone (bass and treble)

balance (Left/Right) processor for quality audio

applications in car radio and Hi-Fi systems.

It reproduces surround sound by using phase

shifters and a signal matrix. Control of all the

functions is accomplished by serial bus.

The AC signal setting is obtained by resistor net-

works and switches combined with operational

amplifiers.

Thanks to the used BIPOLAR/CMOS Technology,

Low Distortion, Low Noise and DC stepping are

obtained.
