Working Principles

The AK5367AEF utilizes a delta-sigma modulation technique to convert analog audio signals into digital form. It employs oversampling and noise shaping to achieve high resolution and minimize quantization noise. The analog input is sampled at a high frequency, and the resulting data is processed through a digital filter to remove unwanted noise and distortions. The converted digital audio is then available for further processing or storage.
