TDA2030 Amplifier Split Supply Circuit Diagram

Introduction

In this article, we will discuss the TDA2030 amplifier split supply configuration and provide a circuit diagram for building one.

The TDA2030 amplifier is a widely used integrated circuit (IC) for building high-quality audio amplifiers. It is capable of delivering up to 14 watts of output power into an 8 ohm load with a 0.5% THD+N distortion level, making it an ideal choice for home stereo systems, car audio systems, and other audio applications. This amplifier can be used with both single supply and split supply configurations.

What is a split supply configuration?

A split supply configuration, also known as a bipolar supply configuration, is a circuit design in which the power supply is split into two equal and opposite polarities. Each polarity is associated with a voltage level, with one polarity being positive and the other being negative. This configuration is commonly used in audio amplifiers as it provides a signal swing that is twice the voltage level of single supply circuits. This results in an increase in the output power of the amplifier and a reduction in distortion levels.

Why use a split supply configuration with TDA2030?

Using a split supply configuration with this amplifier has several benefits. Firstly, it increases the output power of the amplifier compared to single supply configuration. Secondly, the split supply configuration provides a voltage swing that is twice the voltage level of single supply circuits, resulting in a higher signal-to-noise ratio and reduced distortion levels. Thirdly, a split supply configuration provides a ground reference that is halfway between the positive and negative polarities, which is useful for eliminating ground loop hum and noise in audio systems.

Conclusion of TDA2030 Amplifier Split Supply

The circuit configuration is an excellent choice for building high-quality audio amplifiers. It provides several benefits over single supply configuration, including increased output power, reduced distortion levels, and improved signal-to-noise.
