FULLY INTEGRATED SIGNAL PROCESSOR
OPTIMIZED FOR CAR RADIO APPLICA-
TIONS
FULLY PROGRAMMABLE BY I
2C BUS
INCLUDES AUDIOPROCESSOR, STEREO -
DECODER WITH NOISE BLANKER AND
MULTIPATH DETECTOR
SOFTMUTE FUNCTION
PROGRAMMABLE ROLL-OFF COMPENSA-
TION
NO EXTERNAL COMPONENTS
DESCRIPTION
The TDA7400 is the newcomer of the CSP family
introduced by TDA7460/61. It uses the same in-
novative concepts and design technologies allow-
ing fully software programmability through I
2C
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-
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.
