ADUM5410ARWZ-RL7 Overview
Digital isolators are components that transmit digital signals across an isolation barrier, providing galvanic isolation to protect sensitive circuitry from high voltages, ground loops, and noise. They are essential in industrial, medical, and communication systems where safety and signal integrity are critical. The ADUM5410 integrates the isolation barrier and a DC-DC converter, simplifying power and signal isolation in a single package.
Key features include 2.5 kVrms isolation, 150 Mbps data rate, 75 kV/µs common-mode transient immunity (CMTI), and an integrated DC-DC converter with adjustable output voltage. The device supports a wide operating temperature range of -40°C to +125°C and is RoHS compliant. The integrated DC-DC converter provides up to 500 mW of isolated output power, making it suitable for powering isolated side circuitry.
The ADUM5410 uses Analog Devices' iCoupler technology, which combines high-speed CMOS and monolithic transformer technology to achieve reliable isolation. The integrated DC-DC converter uses a push-pull topology with an internal oscillator, providing a regulated output with minimal external components. The device features an enable pin for power management and a soft-start function to limit inrush current.
Typical applications include industrial fieldbus isolation, isolated SPI/UART interfaces, isolated power supplies for sensor systems, and medical equipment requiring safety isolation. The high data rate and CMTI make it ideal for communication interfaces such as RS-485, CAN, and Ethernet.
When designing with the ADUM5410, ensure proper PCB layout with adequate creepage and clearance distances for the isolation rating. Place decoupling capacitors close to the VDD and VDDO pins, and follow the recommended application circuit in the datasheet for optimal performance.

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 the ADUM5410ARWZ-RL7 such that the isolation barrier is not bridged by copper traces. Use a solid ground plane under the device, but split it beneath the isolation barrier to prevent noise coupling. Follow the recommended layout in the ADuM5410 datasheet for best results.
The integrated DC-DC converter requires proper input and output decoupling. Place a 10 µF ceramic capacitor close to the VDD pin and a 10 µF capacitor on VDDO. Additionally, add a 0.1 µF capacitor on both sides for high-frequency noise. Ensure the input supply can provide sufficient current for the output load. The maximum output power is 500 mW; calculate the input current accordingly to avoid overloading the primary supply.
The ADUM5410ARWZ-RL7 dissipates power internally due to the DC-DC converter and high-speed switching. At maximum data rate and output power, the junction temperature can rise significantly. Ensure adequate thermal relief by providing copper pours on the PCB and, if necessary, a thermal via array under the device. The operating temperature range is -40°C to +125°C; keep the junction temperature below 150°C for reliable operation.
