Description
The TDA7404 is a high performance signal
processor specifically designed for car radio
applications.
SO-28
The device includes a high performance
audioprocessor with fully integrated audio filters.
The digital control allows a programming in a wide
range of all the filter characteristics. By the use of
a BiCMOS process and a linear signal processing
low distortion and low noise are obtained.
