® TDA7400
ADVANCED CAR SIGNAL PROCESSOR
FULLY INTEGRATED SIGNAL PROCESSOR
OPTIMIZED FOR CAR RADIO APPLICA-
TIONS
FULLY PROGRAMMABLE BY I2C BUS
INCLUDES AUDIOPROCESSOR, STEREO -
DECODER WITH NOISE BLANKER AND
MULTIPATH DETECTOR
PROGRAMMABLE ROLL-OFF COMPENSA-
TION
NO EXTERNAL COMPONENTS
DESCRIPTION
The TDA7400D is the newcomer of the CSP fam-
ily introduced by TDA7460/61. It uses the same
innovative concepts and design technologies al-
lowing fully software programmability through I2C
bus and overall cost optimisation for the system
designer.
The device includes an audioprocessor with con-
figurable inputs and absence of external compo-
nents for filter settings, a last generation
stereodecoder with multipath detector and a so-

ORDERING NUMBER: TDA7400
phisticated stereoblend and noise cancellation
circuitry.
Strength points of the CSP approach are flexibility
and overall cost/room saving in the application,
combined with high performances.
