ADUM3160BRWZ-RL7 - USB Digital Isolator 2.5kV | Analog Devices
MPN: ADUM3160BRWZ-RL7 ✓ AktifADUM3160BRWZ-RL7 Ringkasan
A USB digital isolator is a component that provides electrical isolation between the USB controller and the USB connector, protecting the host from ground potential differences and electrical noise. It is part of the broader category of digital isolators, which use capacitive or magnetic coupling to transfer digital signals across an isolation barrier without a direct electrical connection. The ADUM3160 specifically uses monolithic air core transformers, a hallmark of iCoupler technology, to achieve high-speed data transfer with low power consumption.
Key features of the ADUM3160BRWZ-RL7 include its 2.5 kVrms isolation rating, 12 Mbps full-speed USB support, and 25 kV/µs CMTI. The device operates from a 3.3 V supply on both sides of the isolation barrier, with a typical quiescent current of 5 mA. It is designed to be compliant with USB 2.0 specifications for low and full speed, making it suitable for isolated USB interfaces in medical, industrial, and instrumentation applications.
Technically, the ADUM3160 integrates a USB transceiver with an isolation barrier, allowing the D+ and D- lines to be isolated while maintaining signal integrity. The device uses a proprietary encoding scheme to transmit data across the isolation barrier, ensuring reliable communication even with high common-mode noise. The SOIC-W package provides excellent thermal performance and is suitable for automated assembly.
Typical applications include isolated USB hubs, medical device interfaces, industrial control systems, and data acquisition systems where ground loop isolation is critical. The ADUM3160BRWZ-RL7 is particularly well-suited for applications requiring full-speed USB data transfer with high isolation voltage.
When designing with this device, ensure that the supply voltages on both sides are within the specified range (3.0V to 3.6V) and that proper decoupling capacitors are placed close to the VDD pins. The device does not require external components for the isolation barrier, simplifying the design.

Catatan Desain
Ensure that both VDD1 and VDD2 are within the specified range of 3.0V to 3.6V. Use 0.1 µF decoupling capacitors close to each VDD pin to minimize noise. For full-speed USB, a 1 µF capacitor on the VBUS side may be required.
Place the ADUM3160BRWZ-RL7 close to the USB connector to minimize trace length for D+ and D-. Maintain controlled impedance for USB lines (90 ohms differential) and avoid vias on these traces. Keep the isolation barrier clear of copper pour to maintain creepage distance.
Do not exceed the absolute maximum ratings for supply voltage or isolation voltage. Ensure that the SPD pin is correctly configured for low or full speed operation. Incorrect SPD settings can cause communication failures.
