STMicroelectronics TDA7719TR

Description
The TDA7719 is a highperformance signal processor specifically designed for car radio applications. It includes a highperformance audio processor 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 linear signal processing, low distortion and low noise are obtained.
