TDA2030 Audio Amplifier Circuit

If you are looking for the best audio amplifier circuit. I prefer the Tda2030 audio amplifier circuit. It is a class AB high-quality audio circuit. most commonly used in the Home theater system.

The ic will be used for 2.1 and 5.1 audio systems, because of the high-end performance of this ic. when compared with cost wise the ic has 20- 70 rupees ( 1$ ) only. you can build the circuit easily. The IC needs a few components for the working. so in this article, I’m going to share the circuits of the Tda2030 amplifier.

Tda2030 audio amplifier IC

About TDA2030 ic

The ic is a monolithic circuit with a petawatt package. The ic allows a wide range of voltage, up to 36v. Using as a low-frequency class AB amplifier. The ic will provide 14w output on 14v / 4ohm. 8 watts output on an 8-ohm speaker.

TDA2030 is a high current output with low distortion. The 5-pin is the next advantage of this ic, it reduces the external components and budget of the amplifier. The tda2030 bridged audio amplifier is mostly used in subwoofer amplifiers.

Detailed information about Tda2030 pinout

PIN NUMBER	PIN NAME	DESCRIPTION
1	-Non-inverting	The audio input pin. The pin in negative and the output goes to positive
2	Inerting pin	The inverting input gives feedback from the output pin.
3	Ground	Ground connection of the ic
4	Output	Output pin of the ic
5	Supply	Minimum 6-12v Maximum 18-36v DC supply.

TDA2030 Audio Amplifier Circuit

TDA2030a 12 watts amplifier circuit

The circuit contains few external components, which will give better audio quality. You can use this circuit as a car audio amplifier. You don’t need to provide any dual power supply to this circuit. The circuit works working a direct connection from the car battery.

TDA2030 Bridged Amplifier Circuit

The TDA2030 Bridged Audio Amplifier Circuit. it is most commonly used in the subwoofer amplifier circuit. it will provide 35w at 8-ohm speaker. this power is pretty good for a small home theater system.

The two tda2030 bridged together the feedback for the second ic will take from the first ic output pin of 2.

200 watts TDA2030 amplifier circuit

In bridged type including 2 pairs of transistors will increase the power of the amplifier circuit. Approximately 200 watts of output will deliver this circuit diagram. if you do not find the transistor in the market use equivalent transistors of Tip 35 and Tip 36.
