Digital Isolators pave the way for robust communication within and between systems. They are widely used as building blocks for signal and data transmissions, providing galvanic isolation between devices. The ADUM142E0BRWZ-RL digital isolator is a high-efficiency, reliable, and cost-effective device that can bridge the gap between integrated circuits using basic CMOS technology.

The ADUM142E0BRWZ-RL’s main application field is data transmission between integrated circuits that are powered at different voltage levels. It provides complete isolation of multiple signals and noise immunity in noisy applications. Apart from this, the isolator can also be used to protect one or both sides of the digital system from ground loops, noise pulses, and other high-frequency interference. In addition, the digital isolator can pass signals in both directions, allowing a bidirectional data transmission.

The ADUM142E0BRWZ-RL offers an isolation rating of 3.75kV, allowing for robust and safe data transmission between integrated circuits. It also features a very low propagation delay of only 6ns for 1MHz input signals, making it ideal for high-speed data transmission and control applications. The digital isolator provides a guaranteed data rate of 250kbps, making it suitable for a wide range of communication protocols. It is capable of handling multiple logic signals and can be used in a variety of configurations to provide up to 8 isolation channels.

In terms of its working principle, the ADUM142E0BRWZ-RL digital isolator uses an optocoupler to isolate input signals. The optical signals from the optocoupler are then processed by a CMOS technology based digital isolator, which can pass the signals to the output through two separate paths. The first path is an electrical connection between the input and output terminals which provides an instantaneous transfer of the signal. The second path is the signal transmission through a magnetically-coupled core using the principle of flux modulation. This method ensures that the signal is fully isolated from the input to the output.

The ADUM142E0BRWZ-RL digital isolator is a reliable and cost-effective solution for bridging the gap between integrated circuits. It is highly efficient in data transmission, offering high speeds and low propagation delays, and is suitable for applications that require isolation between components. With its high isolation rating and wide temperature operating range, the ADUM142E0BRWZ-RL is a reliable and cost-effective choice for many applications.
