USB Isolator FOUR port ADuM3160
4-port USB 2.0 isolator with hub (ADuM3160), 2.5 kV isolation - blocks ground loops and noise
This is a USB to four-USB isolator with an included isolated power supply, supporting USB 2.0 at 1.5Mbps and full speed 12Mbps, combined with a built-in 4-way USB hub. When a PC and external devices (such as a radio's CAT interface or a sound card) share a USB connection, their grounds are also tied together - this can create ground loops that inject hum or RF noise into audio and control lines.
This isolator breaks that direct connection: it passes USB data and power across an isolation barrier without a shared ground, blocking common-mode noise and protecting connected devices from voltage differences. No driver is required, and all ports include ESD protection. An external 5V input is available for powering external USB devices when higher current is needed.
