Description

*The TDA7343 is an upgrade of the TDA7313 audioprocessor.
*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 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.

*The Soft Mute function can be activated in two ways:
   1 Via serial bus (bit D0, Mute Byte)
  2 Directly on pin 22 through an I/O line of the TDA7343*Very low DC stepping is obtained by use of a BICMOS technology.
