DESCRIPTION
The audioprocessor TDA7435 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.
A second programmable high pass filtering pro-
videsthe loudspeakersequalization.
The soft Mute function is implemented andcan be
activated in two ways:
1 Viaserial bus (Mute byte, bit D0)
2 Directly on pin 3 through an I/O line of the mi-
crocontroller
Very low DC stepping is obtained by use of a
BICMOS technology.
