Hifi Audio Amplifier using Tda2030A

TDA2030 Pinout 

The TDA2030A is a monolithic IC in a Pentawatt package intended for use as a low-frequency class-AB amplifier. With VS max = 36V it is particularly suited for more reliable applications without regulated supply and for 35Watt driver circuits using low-cost complementary pairs.And also includes the

protection system from the short-circuit & very high temperature.

Hello Guys, in this Project am going to explain  exactly how you can build your own 2 X 32W TDA2030 Hifi Stereo Power Amplifier, Tda2030A is a monolithic ic in a Pentawatt package intended for use as a low-frequency class-AB amplifier.Typically it provides 14 W output power (d = 0.5%) at 14 V/4 Ω. At ±14 V or 28 V, the guaranteed output power is 12 W on a 4 Ω load and 8 W on an 8 Ω . It is a good IC for creating Audio amplifier.

Let get started use the circuit diagram below to create 2x Channels.

2 X 32W TDA2030 Hifi Stereo Power Amplifier circuit diagram 

Diagram Shows Only One Channel

Large heat sink is required for this circuit.

50K Pot Volume switch can be used for adjusting the volume.

The capacitor 104j connected to 1ohm resistor  helps in avoiding the surplus noises within the speaker

1 Channel can use 2 speakers 30W 4ohm.

For power supply Connect positive to position, negative to negative to single Power supply.
