Typical Applications
ADUM3160BRWZ-RL7 is suitable for 6 applications: Isolated USB Hubs, Medical Device Interfaces, Industrial Control Systems, Data Acquisition Systems, Test and Measurement Equipment, Consumer Electronics with Isolation.
Isolated USB Hubs
The ADUM3160BRWZ-RL7 is ideal for isolated USB hubs, providing galvanic isolation between the upstream and downstream ports. Its 12 Mbps full-speed data rate supports standard USB peripherals, while the 2.5 kV isolation protects against ground loops and voltage transients. The device's high CMTI of 25 kV/Β΅s ensures reliable data transfer even in electrically noisy environments, making it suitable for industrial USB hubs that connect to sensors and controllers.
Recommended
Medical Device Interfaces
In medical devices, patient safety requires galvanic isolation between the patient-connected parts and the main system. The ADUM3160BRWZ-RL7 provides 2.5 kV isolation, meeting safety standards for medical equipment. Its full-speed USB capability allows high-speed data transfer for diagnostic imaging and patient monitoring. The device's low power consumption and small SOIC package make it suitable for portable medical devices.
Recommended
Industrial Control Systems
Industrial control systems often have large ground potential differences between subsystems. The ADUM3160BRWZ-RL7 isolates the USB interface, preventing ground loops that can cause data corruption or equipment damage. Its 25 kV/Β΅s CMTI ensures reliable operation in environments with motor drives and power converters. The device supports full-speed USB, enabling fast communication with PLCs and HMIs.
Recommended
Data Acquisition Systems
Data acquisition systems often require isolation to protect sensitive measurement circuits from noise and ground loops. The ADUM3160BRWZ-RL7 provides a clean USB interface for transferring data to a host computer. Its 12 Mbps data rate is sufficient for streaming high-resolution sensor data. The device's isolation barrier also prevents common-mode noise from affecting measurement accuracy.
Recommended
Test and Measurement Equipment
Test and measurement equipment often needs isolated USB ports to prevent ground loops when connected to devices under test. The ADUM3160BRWZ-RL7 provides 2.5 kV isolation, ensuring safe and accurate measurements. Its full-speed USB support allows fast data transfer for oscilloscopes, multimeters, and spectrum analyzers. The device's robust CMTI ensures reliable operation in EMC-heavy test environments.
Recommended
Consumer Electronics with Isolation
In consumer electronics, isolation can protect against static discharge and ground potential differences. The ADUM3160BRWZ-RL7 is used in devices like isolated USB chargers and audio interfaces. Its small SOIC package and low power consumption make it suitable for compact designs. The device supports full-speed USB, ensuring compatibility with standard peripherals.

Key Differentiators
- iCoupler technology with monolithic air core transformers (vs ISOUSB211)
- Wide-body SOIC package for enhanced creepage (vs ADUM3160BRWZ)
- High CMTI of 25 kV/Β΅s (vs ADUM3160BRWZ)
Design Notes
Ensure that both VDD1 and VDD2 are within the specified range of 3.0V to 3.6V. Use 0.1 Β΅F decoupling capacitors close to each VDD pin to minimize noise. For full-speed USB, a 1 Β΅F 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.
Compliance Information
RoHS compliant per Analog Devices product page. No AEC-Q100 qualification for this part.
