DESCRIPTION
The TDA7404D 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.
