Product Summary

The TDA7000 is a monolithic integrated circuit for mono FM portable radios, where a minimum on peripheral components is important(small dimensions and low costs). The TDA7000 has an FLL (Frequency-Locked-Loop) system with an intermediate frequency of 70 kHz. The i.f. selectivity is obtained 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 precautions are taken to meet the radiation requirements.

Parametrics

TDA7000 absolute maixmum ratings: (1)Supply voltage, VP: max. 12 V; (2)Oscillator voltage, V6-5: VP-0.5 to VP + 0.5 V; (3)Total power dissipation: see derating curve Fig.2; (4)Storage temperature range Tstg: -55 to +150 ℃; (5)Operating ambient temperature range Tamb: 0 to + 60 ℃.
