TDA7391LVPDU is a family of BTL audio amplifier integrated circuits developed by STMicroelectronics. They can be used to supply audio to headphones and small speakers. They are widely used in consumer electronics, such as TVs, Home Theaters and car audio systems.

The TDA7391LVPDU uses a Bipolar Transistor as the active device, which is also known as a BTL or push-pull amplifier. This type of amplifier is known for its high output power, low distortion and wide frequency response. It can be used for applications such as audio amplification, noise-cancelling speakers, and signal mixing. The TDA7391LVPDU supports both Left and Right Channel audio input sources.

The TDA7391LVPDU audio amplifier features several features that allow it to provide superior audio reproduction and signal processing compared to other traditional amplifiers. The first is its low-noise and low-distortion performance, due to its low-noise Bipolar Transistor. This ensures that the audio output is clear and accurate, without noise or distortion. Additionally, the TDA7391LVPDU uses an unequalled circuit topology to reduce output feedback signals, which also prevents audio distortion. In order to further reduce any distortion, the TDA7391LVPDU features an “extended voltage” version, which provides a higher voltage range than most traditional amplifiers.

The TDA7391LVPDU also features a very high signal-to-noise ratio, which is a measure of the ratio between the signal level and the background noise level. This is often a key factor in determining an amplifier’s sound quality. The higher the signal-to-noise ratio, the cleaner and clearer the audio output from the amplifier. Additionally, the amplifier also features a high power output, which means it can drive larger speakers and higher frequencies. This is ideal for home and car audio systems that require higher sound levels.

The TDA7391LVPDU also features several other important features, such as built-in thermal protection, input and output limiters, and a soft-start power-up circuit. The thermal protection prevents the device from overheating, while the input and output limiters prevent any distortion caused by too much input or output. The soft-start power-up circuit provides a smooth, controlled start to the amplifier, reducing any transients or unwanted noise during the start-up sequence. All of these features are designed to make the TDA7391LVPDU a highly efficient, reliable audio amplifier.

The TDA7391LVPDU can be used in many different audio applications. It is ideal for headphone amplifiers, car audio systems, home theatre systems, and digital audio systems. It can also be used in other applications such as soundcards, video conferencing systems, power amplifiers, and active loudspeakers. The TDA7391LVPDU is suitable for many different configurations and can be used in single-ended, balanced, or bridged modes.

In conclusion, the TDA7391LVPDU is an excellent choice for audio amplification needs. It offers superior sound quality, reliability, and efficiency. It is versatile enough for a wide range of applications, and is easy to integrate into existing systems. With its low cost, low power consumption, and high performance, the TDA7391LVPDU is the perfect amplifier for many applications.
