Ne5532 Headphone Amp Schematic

By | September 16, 2023

The NE5532 is a dual operational amplifier (op-amp) that is widely used in audio applications. It is a high-quality op-amp with a low noise floor and a wide bandwidth. It is also relatively inexpensive, making it a popular choice for DIY audio projects. In this article, we will walk you through the process of building a headphone amplifier using the NE5532. We will provide a detailed schematic and instructions, and we will also discuss the different components that you will need for the project. ## What You Will Need To build this headphone amplifier, you will need the following components: * 2x NE5532 op-amps * 1x 100uF capacitor * 2x 10uF capacitors * 2x 100k resistors * 2x 22k resistors * 1x 1k resistor * 1x 0.1uF capacitor * 1x 3.5mm headphone jack * A breadboard or perfboard * Wire * Soldering iron and solder ## Schematic The following is the schematic for the headphone amplifier: ## Instructions To build the headphone amplifier, follow these steps: 1.

Assemble the circuit on a breadboard or perfboard.

Connect the components according to the schematic. 2.

Power the circuit with a 9V battery or power supply.

The positive terminal of the power supply should be connected to the V+ pin on the NE5532, and the negative terminal should be connected to the V- pin. 3.

Connect your headphones to the headphone jack.

The tip of the headphone jack should be connected to the OUT+ pin on the NE5532, and the sleeve of the headphone jack should be connected to the OUT- pin. ## Testing the Amplifier Once you have built the amplifier, you can test it by playing some music through it. You should be able to hear the music clearly through your headphones. ## Adjusting the Volume The volume of the amplifier can be adjusted by changing the value of the 100k resistor. A higher value resistor will result in a lower volume, and a lower value resistor will result in a higher volume. ## Conclusion The NE5532 is a versatile op-amp that can be used in a variety of audio applications. This headphone amplifier is a simple and inexpensive project that you can use to learn more about op-amps and how to use them in audio circuits. ## Resources * [NE5532 Datasheet](https://www.onsemi.com/pub/Collateral/NE5532-D.PDF) * [Headphone Amplifier Tutorial](https://www.instructables.com/id/Headphone-Amplifier-with-NE5532/) * [DIY Audio Projects](https://www.diyaudioprojects.com/)
