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, either via the serial bus (bit D0, Mute Byte),
or directly on pin 22 through an I/O line of the
microcontroller
Very low DC stepping is obtained by use of a
BICMOS technology.
