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.
