TDA7303

Digital controlled stereo audio processor with loudness

Features

■ Input multiplexer:

– 3 stereo inputs

– Selectable input gain for optimal adaption

to different sources

■ Volume control in 1.25dB steps

■ Loudness function

■ Treble and bass controL

■ Four speaker attenuatorS:

– 4 independent speakers control in 1.25dB

steps for balance and fader facilities

– Independent mute function

■ All functions programmable via serial I2C bus

Description

The TDA7303 is a volume, tone (bass and treble)

balance (Left/Right) and fader (front/rear)

processor for quality audio applications in car

radio, Hi-Fi and portable systems.

SO-28

Selectable input gain and external loudness

function are provided. Control is accomplished by

serial I2C bus microprocessor interface.

The AC signal setting is obtained by resistor

networks and switches combined with operational

amplifiers.

Thanks to the used BIPOLAR/CMOS Tecnology,

Low Distortion, Low Noise and Low DC stepping

are obtained.
