Electronics Help Care Amplifier circuit diagram 5 Volt amplifier circuit :
This is a 5-volt amplifier circuit diagram. It runs from 4 volts to 12 volts. It’s a mono diagram. Normally, we can use 5 supplies for this diagram. It’s an easy diagram. It can make 5 watts. We can take the voltage from the USB. Also, we can use a 4.2-volt battery. The output watts depend on the voltage.
5 Volt
Supply voltage: 4V to 12V (up to 18V max) the Output power is ~0.5W (at 9V, 8Ω speaker).
tda7294 amplificador 100w:
This is a TDA7294 amplifier, 100 watts. It’s a mono audio amplifier circuit diagram. This circuit diagram can make 100 watts in bridge mode. We can use a minimum 15-0-15 voltage to a 35-0-35 voltage. For stereo mode, we have to use a dual circuit.
This is the amplifier circuit board with speaker protection using transistors. here use 2sc5200 and 2sa1943. This is the transistor board only here needs an amplifier driver circuit board. It’s a mono amplifier circuit board. Here, use 6 transistors. 2sc5200 and 2sa1943. We can also use another transistor. PNP and NPN transistors. we can use 25-0-25 voltage to 70-0-70 voltage in this circuit.
Every amplifier needs a good voltage and amperes to make a good audio output. a good transformer, the best quality of diode, and the capacitors need to make the best voltage. For home use, the best is the IC-based amplifier. and for outside needs, a transistor amplifier to make high-wattage outputs.
