ADUM242E1BRIZ-RL Digital Isolators and Working Principle

Digital isolators are necessary components necessary to keep digital circuits electrically isolated from one another. The ADUM242E1BRIZ-RL product is a high performance digital isolator that uses RF technology to provide extreme isolation performance. This isolator is suitable for a variety of applications, such as high speed data communication, industrial automation, medical equipment, and digital signal processing. In this article, we will discuss the application field of the ADUM242E1BRIZ-RL and its working principle.

Application Fields

The ADUM242E1BRIZ-RL digital isolator can be used in a variety of situations, such as dangerous industrial, automotive, aerospace, and medical environments. It is designed for isolation in applications with up to 1 Mbps switching speeds and 2.1W read and write power dissipation. The ADUM242E1BRIZ-RL is suitable for use in EMI-susceptible environments, as its design and construction.Safety critical applications, such as medical and industrial automation, require high isolation to ensure that signals remain within the system, away from the outside environment. The ADUM242E1BRIZ-RL digital isolator can provide up to 3750Vrms of system-level isolation, making it ideal for these types of applications.The ADUM242E1BRIZ-RL is also suitable for use in embedded systems. It is specifically designed to provide high isolation between two independent circuits, eliminating the need to add additional components or use complex routing to achieve the required isolation. This makes it very versatile and can save time and money.

Working Principle

The ADUM242E1BRIZ-RL digital isolator uses RF technology to provide extreme isolation performance. The isolator consists of two parts, a transmitter and a receiver. The transmitter converts the logic signals on one side of the isolator to a frequency-shifted signal, which is then transmitted across the isolation barrier to the receiver. The receiver converts the frequency shifted signal back to the logic signals on the other side of the isolator. The signal is converted using a special frequency modulated signal that carries all the information necessary to create the logic level output signal.The ADUM242E1BRIZ-RL digital isolator also has an integrated voltage regulator, which can provide a stable voltage supply to the transmitter and receiver. This ensures that the signal transmitted across the isolator has a consistent amplitude and that it is not affected by external noise or interference.In conclusion, the ADUM242E1BRIZ-RL digital isolator is designed for use in both safety critical and general isolation applications. Its extreme isolation performance makes it suitable for use in a variety of situations, from automotive to embedded systems. Its special RF conversion principle makes it easy to integrate and use, saving time and money in the long-term.
