DESCRIPTION
The TDA7348 is an upgrade of the TDA7318
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
microcontroller
Very low DC stepping is obtained by use of a
BICMOS technology.
