Analog Devices Inc. ADuM3165 & ADuM3166 RMS Digital Isolators

Analog Devices Inc. ADuM3165 and ADuM3166 RMS Digital Isolators are USB 2.0 port isolators implementing ADI’s iCoupler^® technology to dynamically support all required USB 2.0 data rates: low (1.5Mbps), full (12Mbps), or high (480Mbps). The ADuM3165 and ADuM3166 deliver host isolation with automatic speed negotiation and peripheral isolation. The device’s high-speed data is retimed for jitter reduction, needing an external clock signal or crystal input.

The ADI ADuM3165 aids the clock or crystal input on the upstream side, and the ADuM3166 supports the clock or crystal input on the downstream side, offering two flexible options for system design. The low power standby mode for downstream (Side 2) assists applications with limited available power, such as battery-operated peripherals. The upstream (Side 1) standby current meets USB 2.0 requirements for suspended operation.

The ADuM3165 and ADuM3166 RMS Digital Isolators are specified over an extended industrial temperature range of −55°C to +125°C. The isolators are housed in a compact 20-lead shrink small outline package (SSOP) with 5.3mm creepage and clearance.
