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).
