The NJM2073M is an advanced audio power amplifying integrated circuit which includes not only the main amplifying unit but also many other features. As a linear amplifier, it is designed to operate in either stereo or single-channel mode, and has a power rating of 25 watts per channel or 50 watts for single-channel operation. It is also capable of driving both low and high impedance loads with varying output levels depending on the specific load.

The monolithic NJM2073M integrates the driver, amplifier, and output stage, controlling each to provide maximum efficiency and reliability. It is optimized for audio application and includes a built-in DC offset protection circuit, thermal protection circuitry, as well as short circuit protection. With a total harmonic distortion rate of 0.01%, the NJM2073M is an effective solution for portable audio and other audio projects.

The NJM2073M adopts advanced technologies to provide low distortion and high power output levels. It utilizes a dual-gate drive circuit for its input stage, which reduces Miller effect-induced distortion and provides a high input impedance for the amplifier. Furthermore, it features a floating inverting input and a differential output, which allows it to achieve high power gain even when low-impedance loads are connected.

The NJM2073M also has a built-in temperature-sensing mechanism and a temperature compensation circuit. This ensures consistent high-quality audio performance and reliability, even in extreme thermal environments. Additionally, the amplifier offers an adjustable quiescent current and an adjustable bias voltage, allowing for efficient power supply utilization.

In terms of working principle, the NJM2073M operates mainly in linear mode and uses negative feedback control. Its input signal is amplified and then fed to the output stage. The output stage then amplifies the signal further, but maintains the same form of the signal, ensuring maximum fidelity and low distortion. This process is further enhanced by the built-in phase compensator, which is designed to ensure phase stability over different load conditions. The output stage is then regulated by the DC offset protection and the temperature protection.

Overall, the NJM2073M offers a great solution for audio projects such as portable audio, hi-fi audio, or audio signal processing applications. With its powerful output levels and extremely low distortion rates, it can offer superior audio quality without compromising the reliability. Furthermore, its adjustable quiescent current and adjustable bias voltage, coupled with its temperature compensation capabilities, make it an ideal solution for any thermal environment.
