What is USB-ISO-HS

The USB-ISO-HS is a High-Speed isolator designed to provide galvanic isolation between the USB host and device. It protects the connected device from power shocks and helps avoid ground loops, which can be problematic in audio applications.

It supports USB transfer modes: Low (1.5Mbps), Full (12Mbps), and Hi-speed (480Mbps). Hi-speed 480Mbps is particularly required by DACs supporting sample rates higher than 96kHz/24bit, and for multi-channel DACs. This high speed is also utilized by high-speed JTAG adapters and Digital Storage Oscilloscopes.

The USB-ISO-HS can supply up to 350mA to the USB device. For applications requiring more power, an external power supply can be connected to the PWR jack. It is crucial to note that this external power supply will be connected directly to the USB device and must also be galvanically isolated. In most scenarios, the 350mA provided by the USB bus is sufficient, and external power is not needed.

Image Description: A small, black, rectangular USB isolator device labeled 'USB-ISO-HS'. It features a yellow sticker with product details including 'USB 1.1 - 2.0 - 3.0 - 3.1', 'Low Full High speed USB Isolator', '1000 VDC', 'PWR 8-15V', 'USB OUTPUT', 'INPUT', 'CE' certification, 'Made in Bulgaria', and the website 'www.olimex.com'. The device has a USB-A female port on one side and a power input jack labeled 'PWR' on another.
