Power Supply Connection:
- Connect AVDD to the analog supply voltage and DVDD to the digital supply voltage as specified in the parameter table.
- Ensure stable power supplies with appropriate decoupling capacitors close to the device.
I2C Configuration:
- Configure the I2C interface using the provided control registers to set up the codec according to the application requirements.
- Use standard I2C protocol for communication.
Sampling Rate Setup:
- Set the desired sampling rate through the I2C interface within the supported range.
- Verify that the master clock (MCLK) is properly configured relative to the selected sampling rate.
Audio Path Configuration:
- Configure input/output paths, volume levels, and other audio settings via the I2C interface.
- Ensure correct gain settings for optimal signal level.
Power Management:
- Utilize power-down modes when not in use to minimize power consumption.
- Follow recommended sequencing for power-up and power-down operations.
Layout Considerations:
- Maintain a clean layout with short traces for analog signals to reduce noise.
- Separate analog and digital grounds and connect them at a single point near the device.
Testing and Verification:
- After setup, test the device for proper operation using known audio signals.
- Monitor performance parameters like SNR and THD+N to ensure compliance with specifications.
