DESCRIPTION
The audioprocessor TDA7437 is an upgrade of
the TDA731X audioprocessorfamily.
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, and zero-crossing mute are imple-
mented.
The soft Mute function can be activated in two
ways:
1 Viaserial 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
BICMOS technology.
