DESCRIPTION

The audioprocessor TDA7437 is an upgrade of

the TDA731X audioprocessor family.

PIN CONNECTION

PQFP44 and TQFP44

ORDERING NUMBERS:

TDA7437 (PQFP44)

TDA7437T (TQFP44)

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 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

BICMOS technology.
