TEA5551T AM receiver radio circuit

ThisAM radio receiver circuit is based on the TEA5551T monolithic integrated radio circuit which is designed for use as a portable radio receiver with headphones  .
The design of the circuit is very simple and require few external components  .
The TEA5551T radio receiver circuit contains all is needed for a AM 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 .
Main features of the TEA5551T are : low voltage operation (VS = 1.8 V to 4.5 V) , low current consumption (Itot = 5 mA at VS = 3 V) , all pins provided with ESD protection AM part , high sensitivity (Vi = 1.5 mV for Vo = 10 mV) , good IF suppression , dood signal handling (Vi(max) = 80 mV) , switch for AM or other applications , short waveband (> 40 MHz) AF part , fixed integrated gain of 32 dB , few external components required , very low quiescent current , low HF radiation and good AF overdrive performance , 0 to 20 kHz limited frequency response ,  25 mW per channel output power in 32 ohms load.

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 .
