Description

Circuit schematic like in Figure 1 above is Circuit Schematic FM Radio using LM 386 IC and BF494 Transistor. ElectronicsHub site describe that the FM Radio circuit mainly consists of LM386 IC. This is a low voltage audio power amplifier. It has 8 pins. It operates at a supply voltage of 4-12 volts. It has an op-amp internally, which acts as an amplifier. The non-inverting pin is connected to the variable resistor of 10KOhms. Inverting pin of the LM386 IC is connected to the ground. Sixth pin is connected to the VCC. Fourth pin is connected to the ground. Fifth pin is output and is connected to the capacitor which is connected to the speaker or microphone. Another capacitor is connected to ground pin. Sixth pin is the supply pin connected to the supply voltage. This amplifies the incoming frequency modulated signal.
