Linear Amplifiers are widely used in various kinds of electronic systems, and the NJM12902M is one of the most popular amplifiers in this category. It is a high speed, single supply, low power, low noise audio amplifier.

The NJM12902M has several application fields, including signal conditioning for audio, speech, and acoustic measurement applications; linear signal amplification of analog audio and speech signals; and feedback compensation or current limiting in motor controls. In particular, it is highly suitable for use in portable audio, communications, instrumentation, and industrial applications.

Working principle-wise, the NJM12902M is based on Bipolar technology. It is an audio amplifier that is driven by an open-loop differential input stage with a constant current source and an active load. The constant current source provides a steady input offset and low distortion, while the active load ensures low output impedance and low distortion at high frequencies.

The NJM12902M also has advanced protection features, such as output current limiting, thermal shutdown, and short-circuit protection. These features ensure that the NJM12902M is highly reliable and will not get damaged in the event of an overcurrent condition.

In summary, the NJM12902M is an excellent linear amplifier for audio, speech, and acoustic measurement applications. It is highly reliable, and its advanced protection features help ensure safety and performance.
