ADUM3402ARWZ-RL

Digital Isolators

Digital Isolators are an important type of electrical isolator that can transfer digital signals between two electrical circuits with electric isolation. They provide increased safety, enhanced EMI performance, and increased system performance over the other types. The ADUM3402ARWZ-RL are digital isolators designed to achieve high-speed data rates of up to 5 Gbps.

Application Field

The ADUM3402ARWZ-RL digital isolators are an ideal solution for high-speed data transmission applications. They are commonly used for data isolation in a variety of industrial, medical, automotive, and communications applications. They can also be used for signal transmission in optical communication networks, FPGA-based designs, and as protection circuits for LVDS video signals.

Working Principle

The ADUM3402ARWZ-RL digital isolators utilize an integrated transformer-based isolation design. This allows the signal on the line side circuit to be transmitted across the isolator without being affected by voltage or current fluctuation on the load side circuit. The resulting isolation enables the two circuits to be completely isolated from each other, providing increased safety and system performance in applications where voltage transients can cause damage or unexpected behavior.

The operation of the ADUM3402ARWZ-RL digital isolators is based on a transformer coupled optocoupler that is a Galvanically isolated direct drive Opto-Isolator. This allows the digital isolator to drive a wide range of high speed signals at frequencies up to 5 Gbps. The output of the digital isolator is then configured to deliver a clean, distortion-free output signal with 200 kV/μs across the isolation barrier.

The ADUM3402ARWZ-RL digital isolators offer excellent EMI performance, electrical isolation, and minimal power requirements. They provide top-level performance in a wide range of applications and are a great addition to industrial, automotive, and medical systems where increased safety, performance, and data transmission speeds are of paramount importance.
