Instructions for Use:

1. Power Supply:

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

2. Input Connection:

   • Connect the audio signal to the input pins with a signal level between 100mV and 200mV for optimal performance.
   • The input impedance is 10kΩ, so ensure the source impedance is compatible to avoid loading issues.

3. Output Configuration:

   • Connect the output to a 4Ω speaker for maximum power output.
   • Ensure the speaker is rated to handle the maximum output power of 3.0W to prevent damage.

4. Thermal Management:

   • The device should be mounted on a heatsink if continuous operation at high power levels is required.
   • Monitor the operating temperature to ensure it stays within the -40°C to 85°C range.

5. Shutdown Mode:

   • To enter shutdown mode, apply a low signal to the shutdown pin.
   • The shutdown current is typically 1μA, which significantly reduces power consumption.

6. Signal-to-Noise Ratio:

   • To achieve the best signal-to-noise ratio (SNR), use high-quality audio sources and keep the input signal clean and free from noise.

7. Total Harmonic Distortion:

   • Keep the output power within the recommended range to maintain low total harmonic distortion (THD).
   • For critical applications, ensure the THD does not exceed 1.0%.

8. Storage:

   • Store the device in a dry environment with temperatures between -55°C and 150°C to ensure long-term reliability.

9. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal components.
   • Follow standard ESD (Electrostatic Discharge) precautions when handling the device.
