Instructions for Use
Power Supply:
- Connect the power supply (Vcc) between 4.5V and 16V to pin 16.
- Ground (GND) is connected to pin 8.
FM Band Selection:
- Use external capacitors and inductors to tune the FM band.
- Typically, a variable capacitor is used for tuning.
AM Band Selection:
- Use external components to select the AM band.
- A ferrite rod antenna is often used for AM reception.
Audio Output:
- The audio output can be taken from pin 13.
- Connect a speaker or headphones with an impedance of 8Ω for optimal performance.
Antenna Connection:
- For FM, connect a telescopic antenna or a wire antenna to the designated pin.
- For AM, use a ferrite rod antenna connected to the appropriate pins.
External Components:
- Refer to the datasheet for specific values of external components such as capacitors, inductors, and resistors.
- Ensure all components are rated for the operating voltage and current.
PCB Layout:
- Follow the recommended PCB layout guidelines to minimize interference and ensure optimal performance.
- Keep the ground plane large and continuous to reduce noise.
Testing:
- After assembly, test the circuit using a known FM and AM signal source.
- Adjust the tuning capacitors to achieve the desired frequency range.
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 IC.
For detailed specifications and application circuits, refer to the official datasheet provided by the manufacturer.
