The NJU7082BV-TE1# is a high-performance, low-power linear amplifier. It is mainly used in instrumentation, operational amplifiers, buffers, and other small-signal amplifiers that require high accuracy, large signal-noise ratio (SNR), low quiescent current consumption, and fast turn-on response. The device is based on a bipolar complementary enhancement-mode transistor design.

The amplifier’s principal application fields include instrumentation, operational amplifiers, buffers, and audio amplifiers. Its linear gain, low quiescent current consumption, and very low distractions from the input referred noise make it especially suitable for silicon microphone front-end amplifiers and ADC interfaces. The amplifier has an input-referred noise of 5 μVrms and a correspondingly low signal-noise ratio (SNR). Furthermore, it is highly stable and responds rapidly to signal changes, which makes it suitable for applications that require wide dynamic range and excellent signal-to-noise performance such as medical instrumentation, electrocardiography (ECG) and electroencephalography (EEG) systems, as well as signal processing circuits.

The NJU7082BV-TE1# comprises of a set of different components: a bipolar complementary N-channel enhancement-mode transistor, a bias current generator, a bipolar output stage, and an upgradeable temperature compensation. The biasing current generator ensures that the NF-generated quiescent current is maintained at the design level, even when the temperature varies, ensuring a stable performance. This also helps reduce the quiescent current of the device and achieve superior noise performance. The upgradeable temperature compensation feature allows for improved temperature stability and accuracy.

The working principle of the NJU7082BV-TE1# involves utilizing the low-power input stage of the amplifier to produce a larger output signal. The input stage is composed of both an N-channel enhancement-mode transistor and a biasing current generator. The biasing current generator adjusts the quiescent current of the input stage to achieve a consistent output signal regardless of changes in ambient temperatures. The two stages—the biasing current generator and the N-channel enhancement-mode transistor—then combine to produce an output signal that is larger than the input due to the gain of the transistors. The output transistors work to keep the output signal stable.

Finally, the NJU7082BV-TE1# can be used as an upgradeable system, giving high performance and accuracy over a wide range of temperatures. In situations where the utmost accuracy is required, the amplifier can be tuned for optimal results. Additionally, the upgradeable temperature compensation feature ensures that the device provides the best performance in varying temperatures.

In summary, the NJU7082BV-TE1# is an ideal amplifier for applications that require a robust, linear amplifier with high accuracy, low power consumption, and minimal noise distortion. Its use in instrumentation, operational amplifiers, buffers, and audio amplifiers is made possible by its low-power input stage, biasing current generator, and upgradable temperature compensation features. Additionally, its fast response time and wide dynamic range make it ideal for a variety of medical instrumentation applications.
