Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 4.5V to 40V.
   • Connect the positive terminal of the power supply to the Vcc pin and the negative terminal to the GND pin.

2. Input Signal:

   • Apply the audio input signal to the IN+ and IN- pins.
   • The input sensitivity should be between 200mV and 400mV for optimal performance.
   • The input impedance is between 10kΩ and 47kΩ.

3. Output Configuration:

   • Connect the speaker to the OUT+ and OUT- pins.
   • The output power is designed to drive an 8Ω speaker with a power range of 1.5W to 2.5W at 12V supply.

4. Thermal Management:

   • Ensure the operating temperature is within -25°C to 85°C.
   • If the device is used in high-temperature environments, consider adding a heatsink to the package.

5. Standby Mode:

   • To put the device into standby mode, apply a low signal to the STBY pin.
   • The standby current is typically 3mA at 5V supply.

6. Signal-to-Noise Ratio:

   • The signal-to-noise ratio (SNR) is typically between 70dB and 80dB, ensuring clear audio output.

7. Total Harmonic Distortion:

   • The total harmonic distortion (THD) is typically 0.5% to 1.0% at 1kHz, providing high-quality sound reproduction.

8. Storage:

   • Store the device in a dry place with temperatures ranging from -40°C to 125°C.

9. Handling Precautions:

   • Handle the device with care to avoid static discharge.
   • Follow standard ESD (Electrostatic Discharge) precautions when handling the IC.

10. Mounting:

    • Solder the device to the PCB following the recommended soldering profile to ensure reliable connections.
