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.
