Circuit Principle:

The WM8960 is an audio codec used in embedded systems, primarily designed to handle analog-to-digital and digital-to-analog conversion for audio signals. It supports a variety of interfaces, including I2S, I2C, and SPI. Its design is focused on achieving high-quality sound with low power consumption. The device integrates a variety of features, such as stereo line-in and line-out support, microphone inputs, and digital audio interfaces.

The key principle behind the device is to convert audio signals from analog to digital (ADC) for processing in a digital form and then convert the processed digital audio back to analog form (DAC) to be output to speakers or other audio devices. The codec operates with a master clock (MCLK) and can be controlled via the I2C or SPI interface.
