Frequently Asked Questions

Q: What does the ADUM3160 USB Isolator Module do?

A: The ADUM3160 USB Isolator Module creates a galvanic isolation barrier between your USB host (e.g. a computer) and the connected USB device. This blocks ground loops, eliminates electrical noise, and protects sensitive equipment from voltage transients — resulting in cleaner data transmission and improved hardware longevity.

Q: Is this USB isolator compatible with my operating system?

A: Yes. The ADUM3160 USB Isolator is plug-and-play and compatible with Windows, macOS, and Linux. No additional drivers or software installation is required. Simply connect it inline between your USB host and device.

Q: What USB speeds does the ADUM3160 isolator support?

A: The ADUM3160 isolation module supports USB 1.1 Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps) devices. It is best suited for applications such as audio interfaces, MIDI devices, oscilloscopes, and microcontroller boards rather than high-speed data transfer peripherals.

Q: Can I use this isolator for Arduino or Raspberry Pi projects?

A: Absolutely. The ADUM3160 USB Isolator Module is a popular choice among Arduino, Raspberry Pi, and general microcontroller enthusiasts. It protects your development board and your computer from potential electrical faults during prototyping and testing.
