TDA1083 Am radio receiver circuit diagram electronic project

This Am radio receiver circuit is based on the TDA1083 radio IC that can be used to build a simple MF band radio. This AM radio schematic circuit based on the TDA1083 will work in 300kHz 3MHz frequency range. This AM radio receiver circuit is very simple and require few external components. Using the TDA1083 we can make a AM FM radio receiv

er but in this diagram is presented just the AM part. TDA1083 support a wide input voltage range and has a high AM sensitivity. If you don`t want much audio output power than 0. 7W you don`t need to use another audio amplifier stage to increase the audio power because the integrated circuit has a build-in audio amplifier stage. L1 and L2 needs to be placed on the same ferrite support with 10 mm diameters and 100 mm long. The L1 has 80 turns and L2 8 turns ( L2 is placed at 5 mm distance from L1 coil ). L3 has coil has 30 turns on a small piece of ferrite. For all three coils you need to use a 0. 2 mm CuEm wire. For this am radio circuit we need a 4. 5 volts dc power supply. C1 capacitor mounted in parallel with the L1 coil is a 270 pF variable capacitor.
