2 DESCRIPTION

■ 2 SPEAKERS AND 2 RECORD

The TDA7430/TDA7431 is volume tone (bass middle

and treble) balance (Left/Right) processors voice

canceller for quality audio applications in car radio

and Hi-Fi systems.

ATTENUATORS:

– 2 INDEPENDENT SPEAKERS AND 2 INDE-

PENDENT RECORD CONTROL

IN 1dB STEP FOR BALANCE FACILITY

They reproduce surround sound by using pro-

grammable phase shifters and a signal matrix.

– AVAILABILITY OF LOUDSPEAKER EQUAL-

IZATION FIXED BY EXTERNAL COMPO-

NENTS

Control of all the functions is accomplished by se-

rial bus. The AC signal setting is obtained by resis-

tor networks and switches combined with

operational amplifiers. Thanks to the used BIPO-

LAR/CMOS Technology,

– INDEPENDENT MUTE FUNCTION

■ ALL FUNCTIONS PROGRAMMABLE VIA

SERIAL BUS

Low Distortion, Low Noise and DC stepping are

obtained.
