Product overview
Description
The TDA7719 is a high performance signal processor specifically designed for car radio applications. The device includes a high performance audioprocessor with fully integrated audio filters and new Soft Step architecture. The digital control allows programming in a wide range of filter characteristics. By the use of BCMOS-process and liner signal processing low distortion and low noise are obtained.
