DESCRIPTION

The TDA7409 is a high performance signal proces-

sor specificall designed for car radio applications.

The device includes a high performance audiopro-

cessor 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.
