TDA7345
DIGITALLY 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 TDA7345 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.
