Electronics Help Care Amplifier circuit diagram Amplifier circuit using TDA2005:
This is the amplifier circuit using TDA2005. Here are three diagrams using the same IC. 2 diagrams are stereo. One is the bridge mode. The stereo diagram makes 10+10 watts. And bridge mode makes 20 watts. The voltage should be no more than 15 volts.
This is an amplifier circuit diagram using TDA2005. It’s a complete audio circuit board. mono board. This board can make 25 watts in bridge mode. 12-volt-operated audio board. It’s also with a pre-amplifier and bass treble controller. Here are 3 adjustable volumes: 1st one for the main volume, 2nd for the Treble, and another for the Bass.
This is the Speaker protection diagram. It can protect our Speaker from burns. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and this protects the voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker.
This is a 2-transistor amplifier circuit diagram using 2SC5200 and 2SA1943 transistors. This is one of the best pairs of amplifier transistors. This pair transistor can make 150 watts of audio output. It’s a mono audio circuit board. We can use here 25-0-25 voltage to 60-0-60 voltage maximum. positive, negative, and ground voltage needs.
The 2SC5200 (NPN) and 2SA1943 (PNP) are one of the most famous complementary transistor pairs in the world of high-fidelity audio. Originally designed by Toshiba, they are the “gold standard” for DIY and professional Class AB power amplifiers due to their high power handling and linear response.
Details about 2SA1943
2sa1943 Polarity is PNP. The maximum collector power dissipation is 150 Watts. The maximum collector-base Voltage is 250 volts. Max Collector-Emitter Voltage is 250V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 17 amperes.
