Frequently Asked Questions

Q: What does the ADUM3160 USB Isolator Module actually do?

A: The ADUM3160 USB Isolator Module creates galvanic (electrical) isolation between your USB host (e.g., a PC) and a connected USB device. This blocks ground loops, suppresses unwanted electrical coupling, and protects both sides from voltage spikes — ideal for audio equipment, lab instruments, and sensitive DIY electronics.

Q: Is the ADUM3160 USB Isolator Module plug-and-play?

A: Yes! No drivers or software installation are required. Simply connect the isolator board between your USB host and USB device, and it operates transparently at USB 2.0 Full Speed (12 Mbps).

Q: What USB devices is this isolator compatible with?

A: The ADUM3160 USB Isolator Module is compatible with any USB 2.0 Full Speed device, including USB audio interfaces, DACs, Arduino and microcontroller boards, lab instruments, USB hubs, and many other peripherals operating at 12 Mbps or lower.

Q: Can this module be used in a DIY electronics project or enclosure?

A: Absolutely. Its compact PCB form factor makes it easy to integrate into custom enclosures, rack-mount systems, or breadboard setups. It's a favourite among makers and electronics hobbyists for this very reason.
