Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

NJU7015D is a high performance instrumentation amplifier developed by New Japan Radio Co., Ltd. It is widely used in many kinds of instrumentation system such as medical diagnosis, control systems, testing and measurement, etc. It integrates the input floating buffer, high accuracy amplification and high common-mode rejection technology, provides a wide dynamic range in a single package. It is extremely suitable for high performance, low power consumption instrumentation applications.

NJU7015D Application Field

NJU7015D has wide application fields. It is suitable for a variety of applications, such as medical diagnosis devices, testing and measurement equipment, automatic control system, and so on.More particularly, due to its high common-mode rejection ratio (CMRR) and wide dynamic range, it is suitable for high precision measurement, control and feedback of the signal. It is able to provide high accuracy data and strong anti-interference ability to increase reliability and accuracy in environments with high common-mode interference.

NJU7015D Working Principle

The main components of the NJU7015D include an operational amplifier, a differential amplifier, and a voltage feedback amplifier. The operational amplifier has a wide input common-mode range and provides a large noise immunity. The differential amplifier is a two-stage amplification composed of cascaded amplifiers for amplified differential signals, and a single-stage stage for common-mode feedback. The voltage feedback amplifier is a single-stage amplifier that has a wide common-mode range, low noise and non-inverted operations. The output from the voltage feedback amplifier is then fed back to the input stages through a resistive circuit.

The NJU7015D provides excellent accuracy and noise performance with a high common-mode rejection ratio (CMRR) while requiring low power consumption. It integrates an input buffer, high accuracy ground-referenced, low noise amplifier and high CMRR all in one compact package. The high CMRR also gives NJU7015D excellent performance in environments with high common-mode interference. The NJU7015D is optimized for low power consumption, helping to extend product battery life.

Conclusion

The NJU7015D is an instrumentation amplifier developed with wide application fields. With the help of its excellent common-mode rejection ratio and wide dynamic range, it is particularly suitable for high precision measurement and control systems. Moreover, the low power consumption makes it even more preferred option in many types of applications.
