DESCRIPTION
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. BLOCK DIAGRAM SO28 ORDERING NUMBER: TDA7401D Very low DC stepping is obtained by using a BICMOS technology.
