![]() The ADuM4165/ADuM4166 employ Analog Devices, Inc., iCoupler ® technology to combine isolator channels, USB transceivers, power and timing circuits, control logic and internal terminations, pull-ups, and pull-downs into a single, 20-lead, wide-body, increased creepage SOIC_IC package. The EVAL-ADuM4165EBZ and the EVAL-ADuM4166EBZ allow quick and easy evaluation of the ADuM4165 and ADuM4166 USB isolators, allowing direct connection to USB hosts and peripherals without the need for additional components. USB isolator modules and USB cable isolators.Industrial PCs and isolated USB ports for debug or upgrade.Electronic test and measurement equipment.USB peripheral, USB host, and USB hub isolation.The isolators are specified over an extended industrial temperature range of −55☌ to +125☌ and are available in a 20-lead, wide-body, increased creepage SOIC_IC with 8.3 mm creepage and clearance. The upstream (Side 1) standby current meets USB 2.0 requirements for suspended operation. The low power standby mode for downstream (Side 2) supports applications with limited available power, such as battery-operated peripherals. The ADuM4165 supports the clock or crystal input on the upstream side, and the ADuM4166 supports the clock or crystal input on the downstream side, offering two options to best suit the system design. High speed data is retimed for jitter reduction, requiring an external clock signal or crystal input. The devices support host isolation with automatic speed negotiation as well as peripheral isolation. If you need an OEM USB isolator to integrate into your application, see the ISO-1-OEM.The ADuM4165/ADuM4166 are USB 2.0 port isolators, utilizing Analog Devices, Inc., iCoupler ® technology to dynamically support all USB 2.0 data rates low (1.5 Mbps), full (12 Mbps), or high (480 Mbps), as required. If you need a ruggedized USB isolator cable, see the ISO-1R. The USB isolator is shipped with a 1 meter USB A to B device cable and 1.3 meter USB extension cable. ![]() Standard operating temperature range is -20☌ to 60☌ and extended temperature ranges are optional. The ISO-1 is housed in a rugged plastic enclosure with mounting ears that simplify mounting to walls, under counters, or inside panels. The ISO-1 is a USB 2.0 compatible device connecting to the host over a high-speed link and features full-speed (12 Mbps) data rates between the downstream USB device. Simply plug the isolator into an available USB port with the included cable, and it is automatically recognized as a generic USB hub device. Supported in Microsoft Windows, Linux, and other USB aware operating systems, the ISO-1 requires no separate drivers and is easy to install. Convenient high-retention USB connectors prevent accidental cable disconnections. Additionally, the isolator can provide a full 500 mA to a downstream device when connected to a USB port capable of sourcing 1 A, or greater. The isolator provides up to 300 mA to a downstream USB device when connected to a standard 500 mA USB port. The efficient DC/DC design allows energy transfer over the isolation barrier. The ISO-1 is USB bus powered, eliminating the need for external power. The ISO-1 is UL Recognized, in accordance with EN60601-1 3rd Edition, and protects both the data and power lines with 4 kV of medical-grade isolation between the host control system and connected USB equipment. ![]() The SeaISO™ ISO-1 single-port, inline USB isolator offers a simple method of protecting host and field equipment from damaging transients and surges commonly found in commercial, industrial and medical environments.
