This is the TDA2050 MONO BRIDGE amplifier circuit diagram. This is a mono amplifier circuit diagram. Here we can use 12 voltage to 24 voltage. This circuit can make 32 watts of output. here used TDA2050 IC. We also use the TDA2030 IC. Here needs a single voltage is needed.
The TDA2050 is a class AB audio power amplifier IC produced by STMicroelectronics (now discontinued, but still widely used and available as stock/clone). It is commonly used in DIY and commercial audio amplifier circuits due to its simplicity and good performance.

Output Power:Up to 25W RMS into 4Ω at ±18V supply (THD 0.5%).Up to 32W into 8Ω at ±22V supply (with low distortion).Up to 32W into 8Ω at ±22V supply (with low distortion).Supply Voltage:Recommended: ±4.5V to ±25V (max ±25V).Low Total Harmonic Distortion (THD): typically <0.05%.
Power amplifier circuit using transistors:
This is a power amplifier circuit using transistors. It’s a stereo diagram board. Here, use 4 transistors: 2 for the left channel, and another 2 for the right channel. 100+100 watts of output power using 35-0-35 voltage and 5 amperes. We know that Voltage X amperes = watts. So, 35X5=175 watts we can get using 35-0-35 voltage.
High Output Current: up to 5A peak.Thermal shutdown & short-circuit protection.Typical Single-Channel Application. Circuit: Operates with a dual supply (e.g. ±18V).Uses feedback resistors to set gain (e.g., 22k/680Ω for ~33x).Requires decoupling capacitors on supply rails .Often paired with a large heatsink, since it can dissipate significant heat.Do you want me to draw you a schematic diagram of a basic TDA2050 amplifier circuit (hi-fi or guitar amp style)
This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. 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 circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker.
2sc5200 and 2sa1943 transistor amplifier circuit diagram. This is a PNP and NPN amplifier circuit diagram. We used 2sc5200 and 2sa1943. 2sc5200 is an NPN transistor, and 2sa1943 is a PNP transistor. We can use a maximum of 230 volts and 1.5 amperes. But here in this circuit diagram, we can use a maximum of 50 volts. The voltage depends on various circuits. This circuit is for a maximum of 50 volts. We can use a maximum of 1.5 amperes for 1 transistor.
