آی سی TDA7719 یک پردازنده صوتی سه باند برای ضبط خودرو نوع smd می باشد.

3 band car audio processor

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 BCMOSprocess and liner signal processing low distortion and low noise are obtained.
