Typical Applications
ADUM5404ARWZ is suitable for 6 applications: Industrial Fieldbus Isolation, Motor Control Interface, Isolated SPI/UART Communication, Medical Equipment Patient Isolation, Isolated Sensor Data Acquisition, Power Supply Feedback Isolation.
Industrial Fieldbus Isolation
The ADUM5404ARWZ provides galvanic isolation for fieldbus interfaces such as RS-485, CAN, and PROFIBUS. Its integrated DC-DC converter supplies isolated power to the bus transceiver, eliminating the need for a separate isolated supply. With 2500 Vrms isolation and 25 kV/µs CMTI, it ensures reliable communication in noisy industrial environments. The 1 Mbps data rate is sufficient for most fieldbus protocols, and the 16-lead SOIC package fits compact PLC and I/O modules.
Recommended
Motor Control Interface
In motor control systems, the ADUM5404ARWZ isolates the microcontroller from the power stage, protecting low-voltage logic from high-voltage transients. Its integrated DC-DC converter powers the gate driver and feedback circuits on the isolated side. The high CMTI of 25 kV/µs ensures stable operation during fast switching of IGBTs or MOSFETs. The 1 Mbps data rate handles PWM and encoder signals, while the 500 mW output power is sufficient for gate drivers and sensors.
Recommended
Isolated SPI/UART Communication
The ADUM5404ARWZ is ideal for isolating SPI or UART interfaces between microcontrollers and peripheral devices such as ADCs, DACs, or sensors. Its four channels can carry SCLK, MOSI, MISO, and CS signals, while the integrated DC-DC converter powers the isolated side. The 1 Mbps data rate supports most SPI and UART speeds, and the 2500 Vrms isolation protects against ground loops and noise. The compact SOIC package is suitable for space-constrained designs.
Recommended
Medical Equipment Patient Isolation
The ADUM5404ARWZ provides the isolation required for medical devices to protect patients from electric shock. Its 2500 Vrms isolation rating meets basic insulation requirements for many medical applications. The integrated DC-DC converter eliminates the need for a separate isolated supply, simplifying the design of patient monitoring and diagnostic equipment. The low power consumption and small package make it suitable for portable devices.
Recommended
Isolated Sensor Data Acquisition
The ADUM5404ARWZ is used in data acquisition systems to isolate sensors from the main controller, preventing ground loops and noise. Its integrated DC-DC converter powers the sensor and signal conditioning circuitry on the isolated side. The 1 Mbps data rate is sufficient for most sensor interfaces, and the 500 mW output power can drive multiple sensors. The high CMTI ensures accurate data transfer in industrial environments.
Recommended
Power Supply Feedback Isolation
The ADUM5404ARWZ can be used to isolate feedback signals in power supply designs, providing safety and noise immunity. Its integrated DC-DC converter can power the secondary-side control circuitry, eliminating the need for an auxiliary winding. The 1 Mbps data rate is sufficient for PWM feedback signals, and the 2500 Vrms isolation protects the primary-side controller from secondary-side transients.

Key Differentiators
- Integrated DC-DC converter (vs ISO7742DW)
- Lower supply current (vs ADUM5404CRWZ)
- Quad-channel configuration (vs ADUM5401ARWZ)
Design Notes
The integrated DC-DC converter requires proper bypassing on both input and output. Place a 0.1 µF and 10 µF capacitor close to VDD1 and GND1, and similarly on VISO and GND2. The datasheet recommends low-ESR ceramic capacitors for high-frequency noise suppression and larger value capacitors for ripple and regulation.
Maintain adequate creepage and clearance distances on the PCB to meet the isolation rating. The 16-lead SOIC package has a minimum creepage of 7.6 mm, but ensure the PCB layout provides at least that distance between input and output sides. Use a ground plane on each side but do not connect them across the isolation barrier.
The ADUM5404ARWZ dissipates power due to the integrated DC-DC converter. At full load (500 mW output), the power dissipation can be significant. Ensure adequate copper area on the PCB for heat sinking, especially in high-temperature environments. The operating temperature range is -40°C to +105°C, so verify thermal performance in your application.
