TDA7461N  
CAR RADIO SIGNAL PROCESSOR  
HIGH PERFORMANCE SIGNAL PROCES-  
SOR FOR CAR RADIO SYSTEMS  
DEVICE INCLUDES AUDIO PROCESSOR,  
STEREO DECODER, NOISEBLANKER AND  
MULTIPATH DETECTOR  
NO EXTERNAL COMPONENTS REQUIRED  
FULLY PROGRAMMABLE VIA I2C BUS  
LOW DISTORTION  
LOW NOISE  
SO28  
ORDERING NUMBER: TDA7461ND  
DESCRIPTION  
The TDA7461N is a high performance signal  
processor specifically designed for car radio ap-  
plications.  
nents or adjustments. This means that higher  
quality and reliability walks alongside an overall  
cost saving.  
The device includes a complete audioprocessor  
The CSP is fully programmable by I2C bus inter-  
face allowing to customize key device parameters  
and especiallyfilter characteristics.  
and  
a
stereo decoder with noiseblanker,  
stereoblend and all signal processing functions  
necessary for state-of-the-art as well as future car  
radio systems.  
The BICMOS process combined with the opti-  
mized signal processing assure low noise and  
low distortionperformances.  
Switched-capacitors design technique allows to  
obtain all these features without external compo-
