Electronics Help Care Amplifier circuit diagram This is an audio amplifier using the LA4440 IC. This circuit runs using 12 volts. For this, we can use 12 voltage battery. We can use this circuit in a car audio amplifier. It’s a stereo audio amplifier circuit diagram. LA4440 is a common audio IC. We can also use this IC in bridge mode. Here it’s in stereo mode. Left/Right audio Input and Left/right audio Output.
All capacitors are 25 volts. Resistors are 2k2 half-watt. Only some components in this circuit diagram.
This is a mini audio amplifier circuit diagram using the TDA2030 IC. This circuit can make 30 watts of output. It’s a bridge-mode audio circuit diagram. Here, 2 TDA2030 ICs are used. This circuit runs on a minimum 9-0-9 voltage to 18-0-18 voltage. need dual-voltage positive, negative, and ground.
This is an amplifier circuit diagram using transistors. Here, the C5198 and A1941 transistors are used. We can also use other transistors. any pair of NPN and PNP. like 2sc5200 and 2sa1943. It’s a mono audio circuit diagram board. This circuit can make a maximum of 400 watts. It depends on the voltage and amperes. If we use 35-0-35 voltage and 5 amperes. Then we get the output 35X5=175 watts. or 50-0-50 volts and 5 amperes. Then the output will be 50X5=250 watts.
Here on this website, we can get many kinds of amplifier circuit diagrams.
