TDA7000 FM Radio Receiver Circuit


Posted on Feb 4, 2014

GENERAL DESCRIPTION The TDA7000 is a monolithic integrated circuit for mono FM portable radios or receivers where a minimum on peripheral components is important (small dimensions and low costs). The IC 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 onl

y 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.
