ADUM3160BRWZ-R Обзор
A USB digital isolator is a specialized galvanic isolation component that breaks the electrical ground connection between a USB host (PC, hub, or embedded controller) and a USB peripheral, while transparently passing the differential D+/D- data lines and providing isolated VBUS power. ADUM3160BRWZ-R belongs to the digital isolator IC family within interface ICs, sitting hierarchically under USB isolators > digital isolators > interface ICs > integrated circuits. This category is critical in medical, industrial, and test equipment where USB grounds create ground loops or expose sensitive downstream circuitry to fault voltages.
Key features include 2500 Vrms reinforced isolation per UL 1577, 25 kV/us minimum common-mode transient immunity (CMTI), and 7 mA maximum upstream supply current at 1.5 Mbps with 8 mA at 12 Mbps. Operating from a 3.0 V to 5.5 V supply on the upstream side, the device draws minimal quiescent current and provides enhanced system-level ESD performance per IEC 61000-4-x. The wide-body SOIC-16 package offers 8 mm creepage/clearance for high-voltage safety compliance, far exceeding standard SOIC-8 isolators. Internal air-core transformers handle signal isolation, replacing optocouplers with higher bandwidth, lower power consumption, and superior CMTI performance.
Typical applications span isolated USB peripherals, medical device USB ports (patient-connected equipment requiring 2500 V isolation), industrial USB data acquisition modules, USB-to-UART bridges with ground isolation, and test & measurement instruments where USB ground loops would corrupt measurements. Compared with optocoupler-based USB isolation schemes that require separate D+/D- isolators plus discrete drivers, the ADUM3160 integrates the complete USB isolation channel into a single chip, simplifying BOM and PCB layout.
When designing with this part, place 0.1 uF bypass capacitors on both VDDP and VDD3.3 pins within 2 mm of the device. Verify that the application requires only low or full-speed USB - this device is NOT rated for 480 Mbps high-speed USB; for HighSpeed isolation consider ADUM3161 or external solutions. Maintain proper creepage distance on PCB and avoid routing signal traces beneath the package to preserve 2500 Vrms isolation integrity.

Типичное применение
ADUM3160BRWZ-R подходит для 6 применениеs: Medical USB Data Isolation, Industrial PLC USB Programming Port, USB Test and Measurement Instrument, Isolated USB-UART Bridge, USB Isolator Dongle for Field Engineers, Solar PV and Energy Storage USB Monitoring.
Medical USB Data Isolation
The ADUM3160BRWZ-R provides 2500 Vrms reinforced isolation for USB ports on patient-connected medical equipment such as patient monitors, infusion pumps, and ultrasound imaging systems. Its 12 Mbps Full-Speed USB rating supports USB-HID medical peripherals (keyboards, scanners, touchscreens) and USB-UART bridges for diagnostic data transfer, while the 25 kV/us CMTI rejects fast transient noise from MRI gradients or electrosurgical generators. Placed inline between the medical device's MCU and the external USB connector, it isolates both D+/D- data and ground, eliminating dangerous ground loops that could allow fault currents to reach the patient. The wide-body SOIC-16 footprint maintains 8 mm creepage distance required by IEC 60601-1, making it the simplest single-chip path to medical USB isolation compliance.
Рекомендуется
Industrial PLC USB Programming Port
The ADUM3160BRWZ-R isolates the USB programming port of industrial PLCs, motor drives, and process controllers from high-voltage field-side ground faults that could otherwise destroy the upstream engineering laptop. Its iCoupler-based design rejects the 25 kV/us common-mode transients generated by IGBT switching in adjacent motor drive stages, while the 12 Mbps Full-Speed USB supports fast firmware download and HMI configuration. Placed between the PLC's service-port USB PHY and the external USB connector, it ensures a programming laptop never shares ground with 480 VAC or 690 VAC industrial bus rails. The wide-body SOIC-16 footprint provides 8 mm creepage suitable for 230/400 VAC industrial environments without requiring additional isolation barriers.
Рекомендуется
USB Test and Measurement Instrument
The ADUM3160BRWZ-R isolates the USB port of bench-top oscilloscopes, signal analyzers, and data acquisition modules from floating measurement grounds, preventing USB ground loops that would inject 50/60 Hz hum into sensitive analog measurements. With 4.17 uVrms-class noise performance from the upstream supply path and 12 Mbps Full-Speed USB support, it enables USB-TMC (Test and Measurement Class) and USB-HID communications with the host PC without compromising measurement integrity. The 25 kV/us CMTI also rejects fast transients when the instrument probes switching power converter waveforms. Designers typically place it within 5 mm of the USB connector, with 0.1 uF bypass caps on both VDDP and VDD3.3 to maintain rated isolation performance.
Рекомендуется
Isolated USB-UART Bridge
The ADUM3160BRWZ-R pairs with a USB-to-UART converter IC (such as FTDI FT232 or Silicon Labs CP2102) to provide a fully isolated USB-to-serial bridge for embedded debugging, field firmware updates, and industrial sensor networks. Its 12 Mbps Full-Speed USB easily handles 3 Mbps UART rates with substantial margin, while the 2500 Vrms isolation protects laptop USB ports when debugging equipment on high-voltage battery stacks or solar PV arrays. The wide-body SOIC-16 footprint allows the entire bridge to fit in less than 100 mm2 of PCB area, making it ideal for compact isolated debug probe designs. Designers should add a downstream isolated DC-DC converter to provide VBUS power on the peripheral side.

USB Isolator Dongle for Field Engineers
The ADUM3160BRWZ-R enables compact USB isolator dongles used by field service engineers to safely connect laptops to factory equipment, HVAC controllers, and renewable energy inverters without sharing ground. Its single-chip 16-SOIC solution minimizes dongle size while delivering 2500 Vrms isolation sufficient to protect laptop USB ports from 240 VAC rectifier-capacitor stored charge. The 12 Mbps Full-Speed USB rate supports all common USB-UART bridge chips at full speed, enabling field firmware updates without risk to the engineer's laptop. Battery-powered designs can use the upstream-side VBUS only, with no isolated DC-DC needed since USB provides host power on the upstream side.
Рекомендуется
Solar PV and Energy Storage USB Monitoring
The ADUM3160BRWZ-R isolates the USB maintenance port on solar PV inverters, battery management systems (BMS), and EV charging stations that operate at 600-1500 VDC bus potentials. Its 2500 Vrms rating and 8 mm wide-body SOIC-16 creepage provide safe isolation margin against high-voltage battery stacks, while the 12 Mbps Full-Speed USB supports rapid data log retrieval during commissioning. Placed between the inverter's monitoring MCU and the external USB service connector, it prevents dangerous ground paths that would otherwise exist between the laptop and the high-voltage DC bus. The 25 kV/us CMTI also rejects fast transients from IGBT switching in the inverter's power stage, ensuring reliable USB enumeration even during PWM operation.

Заметки по проектированию
Place 0.1 uF X7R bypass capacitors within 2 mm of both VDDP (pin 2) and VDD3.3 (pin 7) to maintain rated isolation performance. Add a 10 uF bulk capacitor on VDDP if the upstream USB host provides only weak 5 V VBUS. Route all high-voltage clearance (creepage) on the PCB to maintain at least 8 mm between the upstream (pin 1-7) and downstream (pin 8-16) sides of the package - the wide-body SOIC-16 itself provides 8 mm but PCB routing must not undercut this.
Do NOT use the ADUM3160BRWZ-R for 480 Mbps High-Speed USB applications - it is rated only for Low (1.5 Mbps) and Full Speed (12 Mbps) USB 2.0. For high-speed USB isolation use ADUM3161 or dedicated high-speed signal-conditioning solutions. Also verify PCB ground split between upstream and downstream domains - any stray trace or copper pour bridging the two sides will defeat the 2500 Vrms isolation rating.
Maintain a continuous ground plane on each side (GND1 for upstream, GND2 for downstream) but leave a clear moat between the two domains. The isolation barrier runs through the ADUM3160BRWZ-R air-core transformer channels - any PCB copper trace crossing this barrier creates a parallel path that reduces effective isolation. Use a 4-layer PCB with power and ground planes to control EMI and provide clean return paths for the differential USB signals.
