Instructions:

1. Power Supply Connection: Connect the appropriate supply voltage between 2.7V and 5.5V to the VDD pin. Ensure stable power supply to avoid any noise or instability issues.

2. Analog Input Configuration: For optimal performance, connect analog signals to the input pins with a sensitivity of around 200mV for full-scale digital output. Adjust gain settings if necessary based on your application requirements.

3. Digital Output Setup: Configure the differential output settings to achieve a signal swing of approximately 2.0Vpp at 1kHz for best audio quality.

4. Noise Considerations: To maintain high signal-to-noise ratio (SNR) of 105dB, ensure that all connections are secure and shielded from external noise sources.

5. Stereo Operation: Achieve a stereo channel separation of 98dB by properly setting up the left and right channels and ensuring minimal cross-talk.

6. Distortion Management: Keep THD+N below 0.0006% at 1kHz to ensure clean audio output without significant distortion.

7. Operational Mode Selection: Choose the operational mode (active, standby, etc.) as per the device's datasheet recommendations to manage power consumption effectively.

8. Reference Design: Refer to the manufacturer’s reference designs and application notes for more detailed setup instructions and advanced configurations.
