Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 4.5V to 16V.
   • Use a stable power source to avoid fluctuations that could affect performance.

2. Standby Mode:

   • To enter standby mode, apply a high level (greater than 1.2V) to the shutdown input (Vshd).
   • In standby mode, the current consumption is minimized to about 20μA.

3. Mute Function:

   • To mute the output, apply a high level (greater than 1.2V) to the mute input (Vmute).
   • This function can be used to prevent popping sounds during power-up or power-down.

4. Input Signal:

   • The input sensitivity ranges from 200mV to 1000mV for optimal operation.
   • Ensure the input signal is within this range to achieve the best audio quality.

5. Output Configuration:

   • Connect the speaker (RL) with an impedance of 8Ω for maximum output power of 220mW at 1kHz.
   • Keep the total harmonic distortion (THD) below 0.5% for high-fidelity sound.

6. Circuit Protection:

   • The IC includes built-in thermal protection to prevent damage from overheating.
   • Ensure proper heat dissipation by using a heatsink if necessary, especially at higher power levels.

7. Layout Considerations:

   • Place decoupling capacitors close to the power pins to reduce noise and improve stability.
   • Use short and wide traces for power and ground connections to minimize inductance and resistance.

8. Storage and Handling:

   • Store the IC in a dry environment to prevent moisture damage.
   • Handle with care to avoid static discharge, which can damage the internal components.
