Instructions:

1. Power Supply:

   • Connect the positive terminal of the power supply to V_CC and the negative terminal to GND.
   • Ensure the supply voltage is within the specified range (4.5V to 5.5V).

2. Input Connection:

   • Connect the audio signal source to the input pins (IN+ and IN-).
   • The input sensitivity is typically 0.5V for full output power.

3. Output Connection:

   • Connect the speaker to the output pins (OUT+ and OUT-).
   • Use an 8惟 speaker for optimal performance.

4. Grounding:

   • Ensure a common ground connection between the power supply, input source, and output load.

5. Thermal Management:

   • The device should be mounted on a heatsink if continuous high power operation is expected.
   • Monitor the operating temperature to ensure it does not exceed 85掳C.

6. Protection:

   • The device includes built-in protection against short circuits and thermal overload.
   • In case of a fault, the device will automatically shut down to prevent damage.

7. Storage:

   • Store the device in a dry environment with temperatures between -65掳C and 150掳C.

8. Handling:

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