TDA7406T Datasheet PDF - STMicroelectronics

DESCRIPTION
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-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.
