Frequently Asked Questions
Q: What does the ADUM3160 USB audio isolator actually do?
A: The ADUM3160-based USB isolator creates a galvanic barrier between your USB host (e.g. computer) and a connected USB audio device. This separates their ground paths and blocks electrical noise — such as ground loop hum and interference — from traveling through the USB connection, resulting in cleaner audio output.
Q: Is this isolator compatible with all USB audio devices?
A: This isolator supports USB Full Speed (12 Mbps) and Low Speed (1.5 Mbps) — the speeds used by the vast majority of USB audio devices including DACs, sound cards, and audio interfaces. Note it does not support USB High Speed (480 Mbps), so it is not suitable for USB 2.0 High Speed storage or video devices.
Q: Do I need to install any drivers to use this module?
A: No. This is a plug-and-play module. Simply connect it between your computer's USB port and your audio device — no software, drivers, or configuration are required.
Q: What is the isolation voltage rating of this module?
A: The ADUM3160 chip provides up to 2500V of isolation, offering a robust electrical barrier between connected devices for both equipment protection and signal integrity.
