1 / 20 page  November 2006 Rev 2 1/20 1 TDA7342 Digitally controlled audio processor Features ■ Input multiplexer – Two stereo and one mono inputs – One quasi differential input – Selectable input gain for optimal adaptation to different sources ■ Fully programmable loudness function ■ Volume control in 0.3dB steps including gain up to 20dB ■ Zero crossing mute, soft mute and direct mute ■ Bass and treble control ■ Four speaker attenuators – Four independent speakers control in 1.25dB steps for balance and fader facilities – Independent mute function ■ All functions programmable via serial I2C bus Description The audioprocessor TDA7342 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.
