Working Principles

The NAU8811YG TR audio codec operates by receiving digital audio data through the I2S or SPI interface. It processes the audio signals using its built-in DSP, which allows for various audio enhancements and effects. The processed audio is then converted to analog signals for playback through the headphone output or line-out. Similarly, the microphone input converts analog audio signals into digital format for recording or further processing.
