Linear - Amplifiers - Audio

The LV47017P-E is an Audio Linear Amplifier designed and manufactured by Texas Instruments. This amplifier is an integrated, single-channel, power amplifier comprised of a low-power input stage and a high-power output stage, making it a great choice for applications that require a combination of low voltage and power. This amplifier is ideal for audio applications such as Hi-Fi, bi-amplification, and multi-channel audio systems. In this article, we will take a look at the Features, Benefits, and Working Principle of the LV47017P-E.

Features of LV47017P-E

The LV47017P-E has several key features that make it stand out. One of these is its versatility – it is designed to work with a broad range of inputs, including digital, analog, and BLUETOOTH audio signal formats. Another feature is its wide gain range, allowing it to be used in multiple audio systems with different input levels. The amplifier has an adjustable gain and cut frequency, allowing users to fine-tune its performance to their needs. Other features include the ability to turn off the output stage with the low power input stage, power-saving in modes, a low-noise signal with very low DC offset and distortion, and thermal protection.

Benefits of LV47017P-E

Given its wide range of features, the LV47017P-E also has several key benefits. Firstly, it is a low-cost amplifier that allows users to reduce costs in their audio production and system design. Additionally, the amplifier is highly efficient and supports high output levels, meaning it can drive a wide range of loud speakers. Furthermore, its low-noise signal makes it suitable for high-fidelity applications such as studio recording, where a low-noise signal is essential. Finally, the LV47017P-E has a compact size and is designed to operate at low power, making it ideal for use with mobile audio systems.

Working Principle of LV47017P-E

The working principle of the LV47017P-E is based on the well-known voltage amplifier concept. This amplifier has two parts – the input stage and the output stage. The input stage is the power amplifier, which is responsible for processing the signal and amplifying the signal to its required level. The output stage is a voltage amplifier, which is responsible for increasing the gain of the signal. The two stages work together to process and amplify the incoming signal, which is then used to drive the speakers.

In order to ensure that the signal is of the highest quality, the LV47017P-E is optimized to reduce distortion and noise levels. The amplifier is also equipped with protection mechanisms that prevent the amplifier from failing due to over-current or over-temperature.

Conclusion

The LV47017P-E is an ideal choice for audio applications that require a combination of low voltage and power. It is a highly efficient, low-cost amplifier that is designed to provide high-fidelity audio signals with low distortion and noise levels. The amplifier supports a broad range of inputs and is optimized to prevent it from failing due to over-current or over-temperature. Overall, the LV47017P-E is an excellent choice for any audio system.
