Description
The TDA7417 is an high performance signal
processor specifically designed for car radio
applications with fully integrated audio filters.
The digital control allows a full programming of
the audioprocessor in a wide range of filter
characteristics.
By using BICMOS-process low distortion and low
noise are obtained.
