DESCRIPTION

The TDA7313 is a volume, tone (bass and treble) balance (Left/Right) and fader (front/rear) processor for quality audio applications in car radio and Hi-Fi systems.

Selectable input gain and external loudness function are provided. Control is accomplished by serial I2C busmicroprocessor interface.

TheAC signalsettingis obtainedby resistor networks andswitches combinedwith operationalamplifiers. Thanks to the used BIPOLAR/CMOS Tecnology,

Low Distortion, Low Noise and Low DC stepping are obtained.

■ INPUT MULTIPLEXER:

- 3 STEREO INPUTS

- SELECTABLE INPUT GAIN FOR OPTIMAL ADAPTION TO DIFFERENT SOURCES

■ INPUT AND OUTPUT FOR EXTERNAL EQUALIZER OR NOISE REDUCTION SYSTEM

■ LOUDNESS FUNCTION

■ VOLUME CONTROL IN 1.25dB STEPS

■ 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
