TDA7342EQ2N is a digitally controlled audio processor with the following 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 independent speakers control in 1.25dB steps for balance and fader facilities, independent mute function, all functions programmable via serial I2C bus.
The TDA7342EQ2N is a digitally controlled audio processor designed as an upgrade to the TDA731X family. It features a highly linear signal processing architecture using CMOS-switching techniques to achieve very low distortion and noise. The device supports multiple input sources, including stereo, mono, and quasi-differential inputs, with programmable gain and loudness functions.
