How do you make a 20W amp?
- Assemble the circuit on a good quality PCB.
- Use 12V DC for powering the circuit.
- K1 can be a 4 ohm, 20W speaker.
- S1 is the standby switch and S2 is the ON/OFF switch.
- LED D2 is a power ON indicator.
- Fit the IC to a proper heatsink.
What are the characteristics of LM 1875 IC?
The LM1875 is a 20W Class AB audio amplifier with a wide operating voltage and high bandwidth. The IC can driver 20W speakers with a maximum current of 4A and can also go to a maximum of 30W. It can operate in both with single rail and dual rail power supply, and has some in-built protection features making it robust.

What is TDA2030 IC?
Description. The TDA2030 is a monolithic integrated circuit in the 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 (DIN45500).
Can I replace TDA2030 with TDA2050?
Yes, no problem. Only difference is TDA2050 can take a bit higher Voltage supply: = max 2x25VDC, rekommended 2×18-22VDC. And that TDA2050 can have more watt power output (more current out) and less distortion than TDA2030.
What is LM1875?
The LM1875 is a monolithic power amplifier offering very low distortion and high quality performance for consumer audio applications. Using an 8 load and ±30V supplies, over 30 watts of power may be delivered. The amplifier is designed to operate with a minimum of external components.

Which transistor is best for audio amplifier?
Best Transistors: BJTs
- #1 NPN – 2N3904. You can find most often NPN Transistors in low-side switch circuits.
- #2 PNP – 2N3906. For high-side switch circuits, you need a PNP style BJT.
- #3 Power – TIP120.
- #4 N-Channel (Logic Level) – FQP30N06L.
How can I make a mobile speaker at home?
All you do is cut two holes into the sides of two plastic drinking cups and insert a toilet paper or paper towel tube. The sound is great and your phone stays upright. Here’s a tip that most sites overlook: cut holes into the bottoms of the cups, too. The sound quality is much better.
