Build a Single Chip FM Radio Circuit Diagram Using IC TDA 7000

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.

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.

TDA7000 Single Chip FM Radio

This fm radio series fm radio receiver circuit that uses a single ic TDA.

Quite easy to make this fm radio circuit, where all functions can be done by IC TDA, so we only add to the technical components only. External components are intended to support so you can determine its own range of frequencies to be used. Actually if you want to have the radio equipment are satisfactory you can buy a radio market. Now this type of radio is very varied and the prices varying as well. To be sure with the money of 30 thousand you can get the fm radio with satisfactory quality. Because now the most sold radio is using digital functions, unlike the more dominant is the first transistor radio. But if you are a hobby with experimental electronics, not the rupiah value but which you consider the value of their knowledge.

For the working principle of this circuit does not really exist that must be addressed because all the functions already performed by the internal circuit is ic TDA. That if we do a surgical series is in the ic, the result will not be much different circuits fm radio receiver in general.
