Instructions for Using TDA8561Q

1. Power Supply:

   • Connect the supply voltage (VCC) to the power pin.
   • Ensure the supply voltage is within the range of 4.5V to 16V.

2. Ground Connection:

   • Connect the ground (GND) pin to the system ground.

3. Input Signal:

   • Apply the input signal to the input pins.
   • The input sensitivity is typically 200mV, so ensure the input signal level is appropriate.

4. Output Connection:

   • Connect the output pins to the speakers or load.
   • The TDA8561Q can drive two 8Ω speakers with up to 50W each.

5. Thermal Management:

   • Ensure proper heat dissipation to prevent overheating.
   • Use a heatsink if necessary, especially under high power conditions.

6. Signal-to-Noise Ratio:

   • The SNR is typically 95dB, which ensures a clean audio output.

7. Total Harmonic Distortion:

   • The THD+N is typically 0.01%, providing high-fidelity audio performance.

8. Operating and Storage Temperature:

   • Operate the device within the temperature range of -40°C to 125°C.
   • Store the device within the temperature range of -40°C to 150°C.

9. Quiescent Current:

   • The quiescent current is typically 20mA, but can go up to 30mA.

10. Input Impedance:

    • The input impedance is typically 47kΩ, ensuring compatibility with various audio sources.

By following these instructions, you can ensure optimal performance and longevity of the TDA8561Q audio amplifier.
