DESCRIPTION
Thanks to the used BIPOLAR/CMOS technology, very low distortion, low noise and DC-stepping are obtained. Due to a highly linear signal processing, using DIP28 SO28 ORDERING NUMBER: TDA7343 (DIP28) TDA7343D (SO28) CMOS-switching techniques instead of standard bipolar multipliers, very low distortion and very low noise are obtained Several new features like softmute, zero-crossing mute and pause detector are implemented.
