NJM084D Application Field and Working Principle

NJM084D is a low-power instrumentation amplifier. It can be used for a variety of applications, ranging from single-supply amplifiers for sensors to gain selectable amplifiers and precision current control. This instrumentation amplifier is manufactured by JRC which is a leading manufacturer of semiconductor devices.Instrumentation amplifiers are electronic devices that amplify an input signal while maintaining high accuracy and low source impedance. They are commonly used in industrial systems, medical equipment, data acquisition systems and test equipment. NJM084D is an integrated circuit that features a low-cost and high-performance instrumentation amplifier. It has a gain selectable feature that allows users to select the desired gain of the amplifier. This instrumentation amplifier also features high-accuracy DC stability and low power consumption.The NJM084D instrumentation amplifier is composed of two operational amplifier (Op-amps) and a gain adjust block. The two Op-amps are connected in a non-inverting amplifier configuration. The non-inverting amplifier configuration gives the amplifier high (DC) stability, low output noise, and low distortion characteristics. The gain adjust block is used to control the gain of the amplifier. It consists of two resistors, R1 and R2. R1 is connected to the non-inverting input of the amplifier and R2 is connected to the feedback of the amplifier. By adjusting the values of R1 and R2, it is possible to adjust the gain of the amplifier.The NJM084D instrumentation amplifier is also equipped with a wide range of protection features, such as thermal shutdown and ESD protection. The thermal shutdown feature is designed to protect the amplifier from thermal overload. It will shut down the amplifier if the temperature of the amplifier exceeds its safe operating temperature. The ESD protection feature is designed to protect the amplifier from electrostatic discharge. This feature prevents static electricity from damaging the amplifier’s internal components.The NJM084D instrumentation amplifier is one of the most popular amplifier design for industrial applications. It is low cost, low power, and highly reliable. It is used to accurately measure and control signals in a variety of industrial systems. It is used in applications where accuracy and precision are of the utmost importance, such as data acquisition systems and test equipment.
