The single TDA2030 with a transistor circuit will provide you with the maximum power output (up to 40w). So in this article and like to share the simple audio amplifier circuit using TDA 2030 and to power transistor amplifier circuit. tda2030 bridged amplifier circuit
TDA 2030 will provide up to 14 Watts in the dual power supply. When you are including to power transistor in the output section of the TDA 2030 will give the maximum power output of 40 watts.
This is enough for making a subwoofer amplifier. If you are looking for the best-class AB amplifier with a low price then you go through this article and know details about how to build a powerful audio amplifier using a few components.
Tda2030 IC specifications
The tda2030a is a monolithic integrated circuit. is available in the petawatt packaging. Typically the mice will provide a 14-watt power output of 14 volts,4 ohms. The guaranteed power output of the integrated circuit is 12 watts. This will depend on the quality of the IC.
- Supply voltages plus or minus 18 (36v)
- Output week current is limited to 3.5 amperes.
- Bridging two ICs is very simple.
- The IC contains a short circuit and thermal shutdown.
The common transistors used with the IC 2030 are BD712 and BD711. The BD 712 is a PNP transistor and the BD 711 is a NPN transistor. It is mainly using power audio. I think to purchase of this transistor is because of the low availability in the market. So I suggest you that replace the NPN transistor with TIP2955 and replace the PNP transistor with TIP3055.
Tip3055 NPN transistor pinout
The tip 3055 is a powerful NPN transistor most widely used in the high-power audio amplifier circuit and switching system.
The arrangement of the tip3055 transistor is shown in the image. The first pin is the base pin, followed by the collector and emitter.
TIP2955 PNP transistor pinout
The tip 2955 is a power PNP transistor and is also a complimentary pair for the tip 3055 transistor. The audio amplifier contains a parallel TIP 2955 and tip 3055 transistor.
The pinout of this transistor is the same as the tip3055 transistor.
Do u have amplifier board kits or assembled amplifier boards
yes do you want contact me
