TDA7402 - ST Microelectronics

TDA7402 CARRADIO SIGNAL PROCESSOR

The device includes a high performance audioprocessor and a stereodecoder-noiseblanker combination with the whole low frequency signal processing necessary for state-of-the-art as well as future carradios. The digital control allows a programming in a wide range of all the filter characteristics. Also the stereodecoder part offers several possibilities of pr.
