Instructions

1. Power Supply Configuration:

   • Ensure that the digital core is powered with a stable voltage between 1.8V and 3.3V.
   • The analog components should be powered with a voltage between 2.7V and 5.5V.
   • The I/O voltage must be within the range of 1.8V to 3.3V.

2. Sampling Rate Selection:

   • Configure the sampling rate according to the application requirements, supporting rates from 8kHz to 96kHz.

3. Audio Path Configuration:

   • Set up the analog input and output paths as required by the application.
   • Use the internal DSP for processing audio signals, including equalization, crossover, and other effects.

4. Class D Amplifier Operation:

   • Connect the speaker outputs to the appropriate pins.
   • Ensure the load impedance is suitable for the maximum output power (4Ω recommended).

5. Standby Mode:

   • To reduce power consumption, enable the standby mode when the device is not in use.
   • The current consumption in standby mode is approximately 10μA.

6. Thermal Management:

   • Ensure adequate heat dissipation, especially when operating at high output power levels.
   • Place the device on a PCB with sufficient thermal vias and copper planes.

7. ESD Protection:

   • Handle the device with care to avoid ESD damage.
   • Use appropriate ESD protection measures during handling and assembly.

8. Software Configuration:

   • Use the provided software development kit (SDK) to configure the device settings via I2C or SPI interface.
   • Refer to the datasheet for detailed register maps and configuration parameters.

9. Testing and Validation:

   • Perform initial testing to verify the functionality of the audio codec.
   • Validate the performance parameters such as SNR, THD+N, and output power.

10. Compliance and Certification:

    • Ensure that the design meets the relevant standards and certifications for audio devices.
    • Consult the datasheet and application notes for specific compliance requirements.
