  • 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: Via serial bus (Mute byte, bit D0) Directly on pin 21 through an I/O line of the microcontroller
    Very low DC stepping is obtained by use of a BICMOS technology.

    Key Features

    • All functions programmable via serial I2C bus
    • Four speaker attenuatorsFour independent speakers control in 1.25dB steps for balance and fader facilitiesIndependent mute function
    • Input multiplexerTwo stereo and one mono inputsOne quasi differential inputSelectable input gain for optimal adaptation to different sources
    • Volume control in 0.3dB steps including gain up to 20dB
    • Fully programmable loudness function
    • Bass and treble control
    • Zero crossing mute, soft mute and direct mute
