Working Principles

The WM8950CGEFL/V operates by receiving digital audio data from a host device through the I2S or PCM interface. The digital audio data is then processed by the on-chip DSP, which performs various audio enhancement algorithms such as noise reduction, echo cancellation, and dynamic range compression. The processed audio is then converted to analog signals using the integrated digital-to-analog converter (DAC) and sent to the appropriate outputs, such as headphones or line-out.
