Instructions for TDA3663/N1,135:

1. Power Supply Connection:

   • Connect the supply voltage (Vcc) between 4.5V and 5.5V to the Vcc pin.
   • Ensure a stable power supply to avoid any interruptions.

2. Standby Mode:

   • To enter standby mode, set the appropriate control pin low. This reduces current consumption to between 1mA and 2mA.

3. Operating Mode:

   • For normal operation, ensure the device is powered with the correct supply voltage. The operating current will be between 10mA and 30mA.

4. Output Configuration:

   • Configure the output stage to match the load impedance for optimal performance and maximum output power of up to 4W.

5. Frequency Tuning:

   • Adjust the tuning circuitry to operate within the FM frequency range of 87MHz to 108MHz.

6. Signal Quality:

   • Monitor the signal-to-noise ratio (SNR) and harmonic distortion (THD) to ensure high-quality audio output. Aim for an SNR above 70dB and THD below 0.5%.

7. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to 85°C to ensure reliable performance.

8. Safety Precautions:

   • Always refer to the manufacturer’s safety guidelines and handle the component with care to prevent damage or malfunction.
