NJM2120M#

Linear Amplifiers: Instrumentation, OP Amps, Buffer Amps

The NJM2120M# is a type of amplifier made specifically for audio and instrumentation applications. This type of amplifier has a wide range of uses, ranging from general-purpose audio signals to analog measurements in laboratory and testing settings. The NJM2120M# is also capable of acting as an op-amp and buffer amplifier, allowing it to be used in applications requiring high-level amplification of low-level signals.

Application Field

The wide range of application fields the NJM2120M# is used in reflects its capability for high-performance operation. It is regularly used in consumer audio systems as a pre-amplification device before noise shaping or other effects are added. It is also frequently used in laboratory and test settings as an analog measurement amplifier, measuring S/N ratios and other forms of audio or instrumentation measurements.

The NJM2120M# provides the ability to act as an op-amp and buffer amplifier, making it ideal for applications that require high-level amplification of low-level signals such as boosting line output signals to drive headphones. It is also commonly used in line level audio systems such as karaoke amplifiers, providing both line-level amplifying and buffering capabilities.

Working Principle

At the core of its operation, the NJM2120M# works in a similar way to other linear amplifiers. It uses transistors to create an electronic signal with a given input, often pre-amplifying or boosting audio signals or analog measurements. This amplified signal is then passed on for further processing, either directly to an output or sent to be shaped and modified by effects.

The NJM2120M# also functions as an op-amp and buffer amplifier, allowing it to work with much lower level signals such as line outputs. In this configuration, the NJM2120M# acts as a voltage amplifier, taking a small voltage and amplifying it. This amplification means that the signal can now travel to a destination without any loss of signal strength, maintaining its original properties.

The NJM2120M# is a versatile amplifier, offering a variety of applications suited to a number of audio and instrumentation measurements. Its ability to act as an op-amp and buffer amplifier makes it well suited for applications requiring high-level amplification of low-level signals. As such, the NJM2120M# has become a popular component in many audio and instrumentation systems.
