An Introduction of the TDA7388 Audio Amplifier


The TDA7388 is a brand new class audio amplifier. Because of its fully compatible PNP/NPN output layout, the TDA7388 output is rail-to-rail voltage fluctuations that are not dependent on the requirement of bootstrap capacitors. The very small number of components allows for a compact collection. It is available in the Flexiwatt 25 bundle. It is powered by only a single 14.4V energy source. MOSFET enhances output. It's characterized by low distortion, minimal noise, and powerful anti-interference capability. It comes with AC as well as DC output short circuits as well as protection against temperature. It offers outstanding performance regarding power consumption, including minimal power usage, reliable operation, and high-quality sound. The TDA7388 audio amplifier is designed to work with the most high-end automotive radios mostly car radios.

Where to Use TDA7388?

The TDA7388 audio amplifier is a device that increases the intensity of sound, making it louder. The car audio amplifier does this by increasing the power of the electrical signals to amplify them. It can be used for any type of speaker set up in your vehicle, but it's most commonly paired with subwoofers which are designed to create low-frequency sounds. 

The TDA7388 audio amplifiers come in many different shapes and sizes, with different power outputs. One popular type of car audio amplifier is the mono amplifier that has only one channel. Mono amplifiers are usually more powerful than their stereo competitors and can output more sound without any disconnects or damage to their components. They are more commonly paired with subwoofers because of the low-frequency sounds they create.
