TDA7461N

® TDA7461N CAR RADIO SIGNAL PROCESSOR HIGH PERFORMANCE SIGNAL PROCESSOR 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 DESCRIPTION The TDA7461N is a high performance signal processor specifically designed for car radio applications. The device includes a complete audioprocessor 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. Switched-capacitors design technique allows to obtain all these features without external compoBLOCK DIAGRAM SO28 ORDERING NUMBER: TDA7461ND nents or adjustments. This means that higher quality and reliability walks alongside an overall cost saving. The CSP is fully programmable by I2C bus interface allowing to customize key device parameters and especially filter characteristics. The BICMOS process combined with the optimized signal processing assure low noise and low distortion performances.
