Typical Applications
ADUM5411ARWZ is suitable for 6 applications: Industrial Fieldbus Isolation, Isolated SPI/UART Interface, Motor Control, Isolated Power Supply for Sensor Interfaces, Medical Equipment Isolation, Isolated Power for Gate Drivers.
Industrial Fieldbus Isolation
The ADUM5411ARWZ provides isolated power and data for fieldbus interfaces such as RS-485, CAN, and PROFIBUS. Its integrated DC-DC converter eliminates the need for a separate isolated supply, simplifying design. With a 150 Mbps data rate and 75 kV/µs CMTI, it ensures reliable communication in noisy industrial environments. The 2.5 kVrms isolation protects against ground loops and voltage transients, making it ideal for factory automation and process control systems.
Recommended
Isolated SPI/UART Interface
The ADUM5411ARWZ is well-suited for isolating SPI or UART communication between microcontrollers and peripheral devices. Its high data rate of 150 Mbps supports fast SPI clocks, while the integrated DC-DC converter powers the isolated side, reducing component count. The 3/1 channel direction ratio provides three forward channels and one reverse channel, ideal for SPI with a single chip-select line. This makes it perfect for isolated sensor interfaces and data acquisition systems.
Recommended
Motor Control
In motor control applications, the ADUM5411ARWZ isolates the control circuitry from the high-voltage power stage. Its high CMTI of 75 kV/µs ensures reliable operation in the presence of fast switching transients from IGBTs or MOSFETs. The integrated DC-DC converter provides a clean isolated supply for gate drivers and current sensors. The 2.5 kVrms isolation protects the low-voltage controller from damage, making it ideal for variable frequency drives and servo drives.
Recommended
Isolated Power Supply for Sensor Interfaces
The ADUM5411ARWZ can provide isolated power and data for sensor interfaces in industrial and medical applications. Its integrated DC-DC converter delivers up to 500 mW, sufficient for powering sensors, amplifiers, and ADCs on the isolated side. The 3/1 channel configuration allows for bidirectional communication, enabling sensor configuration and data readout. The wide operating temperature range of -40°C to +125°C ensures reliable operation in harsh environments.
Recommended
Medical Equipment Isolation
The ADUM5411ARWZ is suitable for medical equipment requiring galvanic isolation for patient safety. Its 2.5 kVrms isolation rating meets the requirements for many medical applications, and the integrated DC-DC converter simplifies the design of isolated power supplies. The high data rate supports communication with sensors and monitors, while the low power consumption helps meet energy efficiency standards. The device's small SOIC-W package is ideal for space-constrained medical devices.
Recommended
Isolated Power for Gate Drivers
The ADUM5411ARWZ can be used to provide isolated power and signal isolation for gate drivers in power converters. Its integrated DC-DC converter generates a floating supply for the high-side gate driver, eliminating the need for a bootstrap circuit. The high CMTI ensures stable operation during fast switching events. The 3/1 channel configuration allows for PWM signals and fault feedback, making it ideal for half-bridge and full-bridge topologies.

Design Notes
For optimal isolation performance, maintain at least 8 mm creepage and clearance distance between the primary and secondary sides on the PCB. Place a 0.1 µF decoupling capacitor close to VDD1 and VISO pins. Use a solid ground plane under the device, but ensure the isolation barrier is not bridged by any copper traces.
The integrated DC-DC converter can deliver up to 500 mW. Ensure the input supply can provide sufficient current, considering the efficiency of the converter (typically around 30-40%). For higher power requirements, consider using an external isolated DC-DC converter instead.
The ADUM5411ARWZ dissipates power internally due to the DC-DC converter. At maximum load, the junction temperature rise can be significant. Ensure adequate thermal relief by providing copper pours on the PCB and consider the ambient temperature when calculating the thermal budget.
