Analog Devices introduced the industry’s first single-IC USB isolator, which simplifies isolated USB-port implementation in system-critical medical and industrial equipment. USB ports provide a standardized, straightforward way to connect and disconnect peripheral devices to and from a computer without rebooting or turning off the system.

Leveraging ADI’s iCoupler® digital isolation technology, the ADuM4160 USB isolator offers 5‑kV rms medical-grade isolation, upstream short-circuit protection, and fully isolated 1.5-Mbps and 12-Mbps data rates. The USB 2.0-compliant device provides fully isolated USB functionality at a fraction of the cost and complexity of current data isolation methods, and makes it possible for medical and industrial design engineers to cut implementation costs by up to 25 percent, reduce the size of designs by as much as 50 percent, and trim development time from months to weeks.
