The NJW1105M is an audio amplifier IC (Integrated Circuit) from NJRC, a Japanese manufacturer with a long history of providing quality ICs for a variety of applications. This particular IC is intended for use in audio amplifiers, and is known for its high quality performance, robust design, and low noise levels. The NJW1105M is a monolithic IC, meaning that it is constructed from discrete components that are integrated onto a single piece of semiconductor material. This construction allows the IC to be smaller, more reliable, and more energy efficient compared to traditional amplifier designs. In this article, we will look at the application field and working principle of the NJW1105M.

The NJW1105M is a low-noise linear amplifier, designed to provide stable and accurate amplification of audio signals. It has a wide range of applications, including audio amplifiers, audio effects units, active speakers, audio mixers, and other audio pre-amps and power amplifiers. The NJW1105M is designed to be used to amplify low-level audio signals, such as microphones, remote radio receivers, and other such audio sources. The IC also has capabilities for filtering, over-temperature protection, and has EMC protection as standard.

The NJW1105M operates on a symmetrical supply, which is typically provided by a single or dual supply voltage. This means that it is reasonably flexible in terms of voltage requirements, and can potentially be used in many different applications.

The NJW1105M is a linear amplifier, meaning that it amplifies an audio signal without introducing any distortion or noise. It is also referred to as a class A amplifier, as it exhibits linear behavior as the input signal is changed. This linear behavior makes it ideal for use in audio applications, where noise and distortion need to be minimized. The IC provides a gain of up to 15dB (decibels), allowing it to provide a significant increase in signal power while maintaining the same low-noise figure.

The NJW1105M is designed to provide stable and accurate amplification of audio signals. It incorporates several features which allow it to do this. These include the use of low-noise transistors, a cascaded gain configuration, and a low-distortion circuit design. It also includes additional protection against over-temperature and/or over-current conditions, and can provide protection against electro-magnetic interference (EMI).

In summary, the NJW1105M is a linear amplifier IC from NJRC which is designed for use in audio applications. It has a wide range of applications, and is known for its high quality performance, robust design, and low noise levels. The IC incorporates a variety of features which are designed to provide a stable and accurate amplification of audio signals, and has additional protection features against over-temperature and/or over-currents, as well as being EMI resistant.
