Description
The TDA7406 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-of-the-art as well as future car
radios is therefore provided.
The digital control allows a full programming not only of the audioprocessor and filter
characteristics but also in the stereodecoder part especially for the adaptation to different IF
devices.
