DESCRIPTION
The audioprocessor TDA7437N is an upgrade of the
TDA731X audioprocessor family.
Due to a highly linear signal processing, using
CMOS-switching techniques instead of standard bi-
polar multipliers, very low distortion and very low
noise are obtained. Several new features like soft-
mute, and zero-crossing mute are implemented.The
soft Mute function can be activated in two ways:
1 Via serial bus (Mute byte, bit D0)
2 Directly on pin 28 through an I/O line of the
microcontroller
Very low DC stepping is obtained by use of a BIC-
MOS technology.
