To day i share cheapest cost FM radio circuit using
IC TDA 7000. This Single Chip FM Radio Circuit Diagram is designed as per the data sheet and the
result is excellent. Ideal for all category of electronic enthusiasts.
The TDA7000 is a monolithic integrated circuit for mono FM portable radios,
where a minimum on peripheral components is crucial. The IC TDA 7000
has a Frequency-Locked-Loop system with an intermediate frequency of 70
kHz. The intermediate frequency selectivity is achieved by active RC
filters. The only function which needs alignment is the resonant circuit
for the oscillator, thus selecting the reception frequency. Spurious
reception is avoided by means of a mute circuit, which also eliminates
too noisy input signals. Special steps are taken to meet the radiation
requirements.
Single Chip FM Radio Circuit Diagram Using IC TDA 7000
Notes
- For L1 and L2 wind 5 turns of 0.6 mm enameled Copper wire on a 4 mm dia plastic former.
- For antenna use a 50mm long insulated copper wire.
- IC TDA 7000 can withstand up to 10 V supply voltage.But I recommend 6V.
- Use an 8 Ohm speaker or Headphone at the audio output.
