Instructions for LA4460:

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 4.5V to 5.5V for optimal performance and reliability.

2. Audio Input:

   • The peak-to-peak audio input voltage should not exceed 0.8V to prevent distortion or damage to the device.

3. Output Configuration:

   • Connect an 8惟 speaker load for rated output power and specified total harmonic distortion (THD).

4. Heat Management:

   • Operate within the temperature range of -40掳C to 85掳C to avoid thermal stress on the component.

5. Quiescent Current:

   • Monitor the quiescent current, which typically ranges from 15mA to 25mA at a supply voltage of 5V.

6. Installation:

   • Follow standard PCB layout practices for audio amplifiers, ensuring proper grounding and decoupling capacitors are used to minimize noise and interference.
