DESCRIPTION
The TDA7401 is an upgrade of the TDA7435
audioprocessor.
Due to a highly linear signal processing, using
CMOS-switching techniques very low distortion
and very low noise are obtained.
Second order high pass and low pass filters with
programmable corner frequencies provide the
loudspeaker equalization.
