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.
