DESCRIPTION

The TDA7318 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 is 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.

INPUT MULTIPLEXER:

- 4 STEREO INPUTS

- SELECTABLE INPUT GAIN FOR OPTIMAL ADAPTION TO DIFFERENT SOURCES

INPUT AND OUTPUT FOR EXTERNAL EQUALIZER OR NOISE REDUCTION SYSTEM

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
