Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the specified range (3.0 V to 5.5 V).
   • Use a stable power source to avoid voltage fluctuations that can affect performance.

2. Standby Mode:

   • To enter standby mode, set the appropriate control pin to a low state.
   • In standby mode, the device consumes minimal current (typically 1.0 mA).

3. Active Mode:

   • To activate the device, set the control pin to a high state.
   • Monitor the active current to ensure it does not exceed typical values (150 mA).

4. Output Configuration:

   • For 8Ω speakers, the device can deliver up to 2.5 W continuous average power per channel.
   • For 4Ω speakers, the device can deliver up to 5.0 W continuous average power per channel.

5. Signal Quality:

   • The signal-to-noise ratio (SNR) is typically 95 dB, ensuring high-quality audio output.
   • The total harmonic distortion plus noise (THD+N) is typically 0.1% at 1 kHz and 1 W output.

6. Input Signal:

   • The differential input sensitivity is 0.5 Vpp to 1.5 Vpp for full-scale output.
   • The differential input impedance is 10 kΩ.

7. Temperature Considerations:

   • The operating temperature range is from -40°C to 85°C.
   • The storage temperature range is from -65°C to 150°C.

8. Electrostatic Discharge (ESD):

   • The device has an ESD rating of 4000 V (human body model).
   • Handle the device with care to avoid damage from static electricity.

9. Mounting and Layout:

   • Follow recommended PCB layout guidelines to ensure optimal performance and thermal management.
   • Use appropriate decoupling capacitors near the power pins to filter out noise.

10. Testing and Troubleshooting:

    • Verify all connections and power supplies before testing.
    • If issues arise, check for proper grounding, correct input signals, and stable power supply voltages.
