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 areobtained.

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
areimplemented.
The Soft Mute function can be activated in two ways of the TDA7348:
1 Viaserialbus(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 BICMO Stechnology.
