DESCRIPTION
The TDA7462 is a high performance audioproc-
essor with fully integrated audio filters. The digi-
tal control allows the programming of all filter
characteristics in a wide range without the need
of external components. New innovative features
are included , a dynamic compression stage to

optimize audio response of CD sources an addi-
tional output channel for subwoofer and a sepa-
rate source selector for rear channel. The use of
a dedicated BICMOS process makes signal proc-
essing very linear thus achieving low distortion
and low noise figures.
