Audio Processor 32-Pin TQFP Tray

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.
