Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the specified range of 4.5V to 5.5V.
   • Use a stable power supply to avoid voltage fluctuations that can affect performance.

2. Quiescent Current:

   • The quiescent current is typically 10mA when no load is connected and VDD is 5V. This value should be considered in power budget calculations.

3. Output Power:

   • For optimal performance, operate the device with an 8Ω load. The typical output power is 3.5W at this load with a THD+N of 1%.

4. Efficiency:

   • The efficiency is maximized at 90% when operating at 3.5W into an 8Ω load. This high efficiency helps in reducing heat dissipation.

5. Signal-to-Noise Ratio (SNR):

   • The SNR is 105dB, which indicates a high-quality audio signal with minimal noise.

6. Total Harmonic Distortion + Noise (THD+N):

   • At 1kHz and 1W into an 8Ω load, the THD+N is 0.005%, ensuring minimal distortion in the audio output.

7. Input Sensitivity:

   • The input sensitivity is 300mV for 1kHz at 1W into an 8Ω load. Adjust the input signal level accordingly to achieve the desired output power.

8. Input Impedance:

   • The input impedance is 10kΩ, which allows for easy integration with various audio sources.

9. Operating Temperature:

   • The device operates reliably within the temperature range of -40°C to 85°C. Ensure adequate cooling if operating in high-temperature environments.

10. Storage Temperature:

    • Store the device in an environment where the temperature ranges from -65°C to 150°C to prevent damage.

Additional Notes:

• Always refer to the datasheet for detailed specifications and application notes.
• Proper PCB layout and decoupling capacitors are crucial for stable operation and optimal performance.
