USB isolation for industrial and debug use

The BESIGN USB Isolator ADUM3160 is a two-piece set of USB-to-USB adapter boards that provide galvanic isolation between a host computer and a connected peripheral. Each module uses the ADUM3160 digital isolator to break ground loops and protect sensitive equipment from voltage spikes up to 5 kV ESD. The integrated power isolator supplies up to 1 W to the downstream device, making the pair suited for industrial USB instruments and USB debugging hardware in electrically noisy environments.

Suited for low and full-speed USB gear.

These isolators operate only at USB 1.0, 1.1 and USB 2.0 full-speed rates of 1.5 Mbps and 12 Mbps. They are appropriate for developers isolating a USB debug probe, engineers protecting industrial sensors, or technicians working in noise-sensitive areas where ground-loop interference must be eliminated. Buyers who need to isolate USB 2.0 high-speed peripherals operating at higher signalling rates should look at a different isolation solution because this hardware does not support that mode.

Low and full-speed data rate of 1.5 Mbps and 12 Mbps

The single specification that determines compatibility is the supported USB signalling speed. The ADUM3160 chip inside each board handles only low-speed (1.5 Mbps) and full-speed (12 Mbps) traffic, so any device that enumerates as USB 2.0 high-speed will not function through these isolators. Confirm that your target peripheral operates at low or full speed before purchasing.

Questions about this item

Will the 12 Mbps full-speed rate limit my USB 2.0 high-speed peripherals?

Yes, this isolator only supports low and full speed at 1.5 Mbps and 12 Mbps, so USB 2.0 high-speed devices will not work.

Does the ADUM3160 chip provide galvanic isolation on the USB data lines?

The ADUM3160 uses monolithic air core transformer technology to isolate data and power, protecting connected equipment from ground loops and transients.

What physical space does each isolator module need inside an enclosure?

The module is a compact USB-to-USB board that plugs inline between a host port and a device cable, requiring only the depth of a standard USB connector.
