AM FM portable radio using LA1800

An very simple portable am fm portable radio circuit can be designed using the LA1800 IC and some other external components . As you can see in this circuit diagram ,the LA1800 manufactured by Sanyo Semiconductors , require few additional components and is very easy to design .
The LA1800 am fm portable radio circuit needs to be powered from a 3 volt DC power supply circuit , you can use an 3 volt battery .
This radio receiver circuit has a low current dissipation of 5.6mA for FM band and 3.2mA for AM band .

Also the output signal is driven into earphone speakers , but you can use an additional speaker ( in that case you need to connect an additional small power audio amplifier ) .
