TDA7342 is a digital controlled audio processor from ST company. It has input multiplexer, fully programmable loudness function, 0.3dB step volume control, zero crossing mute, soft mute and direct mute, bass and treble control, four independent speaker control, independent mute function and so on.
The TDA7342 is a digitally controlled audio processor designed as an upgrade to the TDA731X family. It features a highly linear signal processing using CMOS-switching techniques to achieve very low distortion and noise. The device includes an input multiplexer for stereo and mono sources, selectable input gain, and programmable loudness functions.
