Part Details:

TDA7342EQ2N 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 TQFP32 up to 20dB Zero crossing mute, soft mute and direct mute Bass and treble control Due to a highly linear signal processing, using Four speaker attenuators CMOS-switching techniques instead of standard ­ Four independent speakers control in bipolar multipliers, very low distortion and very 1.25dB steps for balance and fader facilities low noise are obtained. Several new features like ­ Independent mute function softmute, and zero-crossing mute are All functions programmable via serial I2C bus implemented. The soft Mute function can be activated in two ways: Description 1. Via serial bus (Mute byte, bit D0) 2. Directly on pin 21 through an I/O line of the The audioprocessor TDA7342EQ2N is an microcontroller upgrade of the TDA731X audioprocessor family. Very low DC stepping is obtained by use of a BICMOS technology.
