The ADUM5412ARWZ can be used to isolate RS-485 transceivers, providing galvanic isolation for industrial networks. Its high CMTI of 75 kV/Β΅s ensures reliable operation in noisy environments. The integrated DC-DC converter supplies power to the isolated side of the transceiver, simplifying the power architecture. With 150 Mbps data rate, it supports high-speed RS-485 communication, making it suitable for factory automation and building control systems.
Recommended
Isolated CAN Bus Interface
The ADUM5412ARWZ is well-suited for isolating CAN bus transceivers in automotive and industrial applications. Its 150 Mbps data rate far exceeds CAN's 1 Mbps requirement, providing ample margin. The integrated DC-DC converter powers the isolated side, reducing external components. The high CMTI ensures robust operation in the presence of motor noise and other transients. This makes it ideal for electric vehicle battery management systems and industrial motor drives.
Recommended
Isolated Power Supply for Sensors
The ADUM5412ARWZ integrates a DC-DC converter that can provide up to 500 mW of isolated power, making it ideal for powering isolated sensor circuits. This eliminates the need for a separate isolated power module, saving board space and cost. The device can be used to power isolated amplifiers, ADCs, or digital sensors while providing data isolation. Its wide supply range of 3.0V to 5.5V accommodates various system voltages, and the regulated output ensures stable sensor operation.

Design Notes
For the ADUM5412ARWZ, maintain proper creepage and clearance distances on the PCB to meet the 2.5 kVrms isolation rating. The SOIC-W package has a minimum creepage of 7.6 mm, so ensure the PCB layout provides at least this distance between primary and secondary side traces. Use a slot or cutout under the device to increase creepage if needed.
The integrated DC-DC converter requires external capacitors for stability. Place a 1 Β΅F capacitor on VDD1 and VDD2, and a 10 Β΅F capacitor on VISO. Use low-ESR ceramic capacitors placed close to the pins. The converter can deliver up to 500 mW; ensure the input supply can handle the load current.
At maximum output power (500 mW), the ADUM5412ARWZ may dissipate significant heat. The SOIC-W package has a thermal resistance of approximately 60Β°C/W (typical). Ensure adequate copper area on the PCB for heat dissipation, and consider airflow if operating at high ambient temperatures. Monitor junction temperature to stay within the -40Β°C to +125Β°C range.
