Instructions for Use:

1. Power Supply:

   • Connect VDD to a stable power supply within the range of 2.7V to 5.25V.
   • Connect VIO to a stable I/O voltage within the range of 1.65V to 5.25V.

2. Digital Audio Interface:

   • Configure the data interface (I2S, Left-Justified, Right-Justified, TDM) using the appropriate control settings.
   • Ensure the sample rate is set within the supported range of 8kHz to 192kHz.

3. Headphone Driver:

   • Connect the headphone output to the desired headphones with impedance between 16Ω and 600Ω.
   • Adjust the output volume to avoid clipping and ensure optimal performance.

4. Power Management:

   • Use the power-down mode to reduce power consumption when the device is not in use.
   • Monitor the power consumption to ensure it remains within the typical range of 45mW at 3.3V and 48kHz.

5. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to 85°C to ensure reliable performance.

6. Mounting and Handling:

   • Handle the SSOP package with care to avoid damage to the pins.
   • Follow standard PCB design guidelines for proper mounting and soldering.

7. Testing and Validation:

   • Perform initial testing with a known good signal source to verify functionality.
   • Validate the SNR and THD+N performance to ensure they meet the specified values.

8. Documentation:

   • Refer to the datasheet and application notes for detailed information on configuration, troubleshooting, and advanced features.
