TDA4350X

Audioprocessor TDA 4350X 1 1.1 Overview Features Stereo-Soundprocessing Three stereo AF inputs, one of the inputs is equipped with floating ground. P-DSO-28-1 Input level control for individual level setting of the several AF sources in addition with a clipping detector. Volume control with software controlled switchable loudness function. Frequency response fixed by external components. Bass- and treble control with clipping detector. Four independent settable output attenuators for balance/fader function. Fan-out of the AF outputs software controlled. AF outputs switchable for driving bride power amplifiers. I2C Bus controlled immediately, or zero cross detector dependent mute, or immediately mute via extra pin. Control Part I2C Bus interface Control of sound processing Read out of the clipping detector status. Type TDA 4350X 1.2 Application Ordering Code Q67000-A5060 Package P-DSO-28-1 The TDA 4350X is a single-chip audio-soundsystem. The circuit can be partitioned into two functional blocks: stereo-soundprocessing and control part.
