Digital isolators are devices used to separate digital signals with no galvainc coupling. These signals improve the controllability and throughput of the communication and data transmission while maintaining EMI/EMC levels that meet industrial requirements. The ADUM161N0BRZ is a high-performance optically-coupled isolator that offers a wide range of benefits in various applications.

Overview

The ADUM161N0BRZ is a digital opto-isolator manufactured by Analog Devices. It is a high-performance, low-cost isolation device designed for various digital-signal applications. This device includes two channels—an isolator channel, which provides maximum isolation between the controlled logic signals, and a low-voltage line driver channel. The isolator is used to provide a high-speed signal transmission between a microcontroller and peripheral devices while ensuring minimum electromagnetic interference (EMI) and electromagnetic compatibility (EMC) requirements.

Application Field

The ADUM161N0BRZ is ideal for various industrial applications, such as communication systems, factory automation, and medical equipment. It has the ability to provide high-speed data transmission, up to 2 Mb/s, with a high signal-to-noise ratio. It can also provide high isolation guarantees in electrically noisy environments.

The ADUM161N0BRZ is also widely used in industrial control systems to guarantee the accuracy of delivered commands and signals, increase system performance, and improve monitoring accuracy. It is commonly used in factory automation systems to provide high-speed transmission between microcontrollers and various sensors and actuators.

Working Principle

The ADUM161N0BRZ utilizes optical isolation, involving the transfer of a digital signal using an optical transmitted signal. Optical signals require a light source, such as an LED, to convert the digital output signal into an optical signal. The optical signal then passes through the isolator and is detected by an optical detector at the input side of the isolator.

The optical detector then translates the optical signal into a regulated voltage level at the input side of the isolator. This voltage is used to drive the switching element at the output side of the isolator, where the digital signal is then converted back into an electrical signal and transmitted to the receiving end.

Conclusion

The ADUM161N0BRZ is a high-performance optically-coupled isolator that offers various features and benefits suitable for industrial applications. It increases system accuracy and performance, reduces EMI and EMC levels, and offers high-speed data transmission with minimal noise. This isolator can improve the control and performance of various industrial applications.
