ORDERING NUMBER: TDA7462D

DESCRIPTION

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.

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
