Digital isolators are used in many applications, particularly when electrical signals need to be electrically isolated from each other. One example of a digital isolator is the ADM2682EBRIZ-RL7, which has applications in the automotive, industrial, and medical fields. This article will discuss the application field and working principle of this digital isolator.

Application Field: The ADM2682EBRIZ-RL7 is a digital isolator that provides isolation in an automotive, industrial, or medical application. The isolator is designed to be used in circuits where electrical signals need to be electrically isolated from each other. It can be used to separate digital signals, such as CAN, LIN, and RS232 signals, as well as analog signals, including current, voltage, and temperature signals. The isolator can also be used in power systems, such as PC Motherboard power supply circuits and CAN Bus circuits. The isolator is suitable for use in harsh environments, including temperatures ranging from -40°C to +125°C, and is able to withstand up to 500 V rms and 3,000 V peak of continuous isolation voltage across an insulated photodiode.

Working Principle: The ADM2682EBRIZ-RL7 employs a dual photodiode and LED design that allows the digital signals to be isolated from each other. This isolator acts as a bridge between an electrical input and output. When there is a difference in voltage applied to the digital input and output, the LED emits light which is then detected by the photodiode, allowing the signals to be isolated. The isolator also has a built-in surge protection circuit that protects against surge voltages up to 400 V. Additionally, the isolator has an integrated common mode choke that limits the noise level, allowing the digital signals to maintain their integrity.

The ADM2682EBRIZ-RL7 digital isolator is a versatile, cost-effective solution for isolating digital and analog signals in automotive, industrial, and medical applications. It is designed to provide reliable electrical isolation for signals, and its built-in surge protection and common mode choke make it suitable for use in hostile environments. The isolator offers a long product life and high level of performance, making it an ideal choice for a range of applications.
