TDA7406T - ST Microelectronics

TDA7406T CAR RADIO SIGNAL PROCESSOR

The device includes a high performance audio processor with 7 bands equalizer and spectrum analyzer plus a stereo decoder-noiseblanker. The whole low frequency signal processing necessary for state-ofthe-art as well as future car radios is therefore provided. The digital control allows a full programming not only of the audioprocessor and filter characterist.
