• Introduction

The LM4895IBP/NOPB is a linear amplifier commonly used in audio applications. It is a monolithic power amplifier with low power consumption, low noise and low distortion. It is designed for applications where high power and high signal fidelity are needed. The amplifier provides low-level inputs and amplified outputs at full power.

• Features

The LM4895IBP/NOPB offers a wide range of features to ensure maximum performance and reliability. These include an operating voltage range of 4.5V to 36V, unity-gain bandwidth of 1MHz, a full-power bandwidth of 1kHz, and a distortion of 0.08%. The amplifier also provides a low supply current of 6mA and a total harmonic distortion of 0.03%. The LM4895IBP/NOPB also features soft-start, short circuit protection, and thermal protection. The amplifier is designed to maintain performance even at higher temperatures. Other features include low output impedance, low harmonic distortion, and high input impedance.

• Applications

The LM4895IBP/NOPB is suitable for use in a variety of audio applications. It is particularly well suited for portable audio systems such as smartphones and MP3 players. It can also be used in high-end hi-fi systems, in-car sound systems and computer speakers. The LM4895IBP/NOPB can also be used in power audio amplifiers, which are used in medium-to-large public address systems.

• Working Principle

The LM4895IBP/NOPB is a linear amplifier designed to provide high performance while consuming low power. The amplifier features an audio input, a power supply, and an audio output. It is powered by a single supply voltage ranging from 4.5V to 36V. The input signal is amplified by a high-gain differential amplifier that is capable of providing gains up to 100x.The LM4895IBP/NOPB amplifier includes a bias control that allows fine tuning of the amplifier gain. The bias is adjusted by changing the supply current passing through two transistors, known as the forward bias legs, within the amplifier. The bias current is kept low to reduce the noise at the output of the amplifier while providing optimal gain.The LM4895IBP/NOPB is also designed to provide robust short-circuit protection. In the event of a short-circuit, the amplifier will shut off the power supply and go into a protection state. The amplifier can then be reset to normal operation by applying power again.

• Conclusion

The LM4895IBP/NOPB is a linear amplifier commonly used in audio applications. It offers a wide range of features, including low power consumption, low noise and low distortion, high-gain differential amplifiers, fine-tuning of the amplifier gain and robust short-circuit protection. It is ideal for use in portable audio systems, hi-fi systems, in-car sound systems and public address systems. The LM4895IBP/NOPB is powered by a single supply voltage and can provide gains up to 100x.
