Description

The audioprocessor TDA7342EQ2N 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. Several new features like softmute, 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 21 through an I/O line of the microcontroller Very low DC stepping is obtained by use of a BICMOS technology.
