Additional Details:

The WM9715LGEFL typically uses an I2C interface for control and configuration. The specific performance characteristics, such as THD+N (Total Harmonic Distortion plus Noise) and SNR (Signal-to-Noise Ratio), vary depending on the operating conditions. It is crucial to consult the manufacturer's datasheet for precise specifications and application guidelines. The datasheet provides detailed information on register settings, timing diagrams, and layout recommendations. Proper power supply decoupling is essential to minimize noise and ensure stable operation.
