Description

* The audioprocessor TDA7435 is an upgrade of the TDA731X audioprocessor family.
* 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 provides the loudspeakers equalization.
*The soft Mute function is implemented andcan be activated in two ways:
      1 Via serial bus (Mute byte, bit D0)
      2 Directly on pin 3 through an I/O line of the microcontroller
*Very low DC stepping of the TDA7435 is obtained by use of a BICMOS technology.
