Tda7000 Fm Receiver. The ic has an fll frequency locked loop system with an intermediate frequency of 70 khz. The difference is that there s only one tuned circuit.
Fm receiver with tda7000 fm radio circuit tda7000 general description 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. This is important in the model t environment where ignition interference is severe. Also the tda7000 is a proper fm receiver and has better interference supression unlike super regen sets which are am receivers.
The advantage of this type of oscillator is that you can use regular 100k potentiometer to precisely tune to a given broadcast.
The tda7000 can also be used as receiver in equipment such as cordless telephones cb radios radio controlled models paging systems the sound channel of a tv set or other fm demodulating systems schematic of the fm radio diy circuit with tda7000 schematic of the fm radio circuit with tda7000. Frequency is tuned by varying the input voltage to the oscillator.

Finally the sensitivity is better meaning less fading of fm stations whilst driving around.
