AM radio receiver circuit using TEA5551T
An AM radio receiver circuit which is designed for use as a portable radio receiver with headphones can be designed using TEA5551T monolithic integrated radio circuit .
The TEA5551T AM radio receiver circuit contains all is needed for a radio receiver circuit (a complete AM part and dual AF amplifier with low quiescent current).
The TEA5551T support a input voltage range (VS) from 1.8 V to 4.5 V but the typical voltage is 3 volts .
Because in most case we don’t find to buy inductors you need to build the inductors L1 , L2 , L3 . In the picture bellow you can see the construction data for these three inductors .
