Typical Applications
ADUM1411ARWZ is suitable for 6 applications: Industrial Field Bus Isolation, SPI Isolation, Motor Control, Power Supply Isolation, Medical Equipment Isolation, Communication Interface Isolation.
Industrial Field Bus Isolation
The ADUM1411ARWZ provides galvanic isolation for field bus interfaces like RS-485 and CAN. Its 3750Vrms isolation and 25kV/µs CMTI ensure reliable communication in industrial environments with ground potential differences and electrical noise. The 1Mbps data rate is sufficient for most field bus protocols, and the 3/1 channel configuration can isolate TX, RX, and control signals. The wide supply range allows direct interfacing with 3.3V or 5V logic. Compared to optocouplers, it offers faster speed, lower power, and better reliability. Place the isolator near the bus connector to minimize noise coupling, and use proper termination resistors on the bus lines.
Recommended
SPI Isolation
The ADUM1411ARWZ is ideal for isolating SPI buses between microcontrollers and peripheral devices. Its 3/1 channel configuration matches the MOSI, MISO, SCLK, and CS signals, and the 1Mbps data rate supports most SPI applications. The low propagation delay of 100ns ensures minimal signal skew, maintaining data integrity. The device operates from 2.7V to 5.5V, allowing level shifting between different logic domains. Use it to isolate sensors, ADCs, or memory devices in noisy environments. Ensure the ground planes are separated and the isolation barrier is maintained in the PCB layout. The high CMTI prevents false triggering from fast transients.
Recommended
Motor Control
In motor control systems, the ADUM1411ARWZ isolates the low-voltage control circuitry from the high-voltage power stage. Its 3750Vrms isolation protects the microcontroller from voltage spikes and ground bounce. The 25kV/µs CMTI ensures reliable operation in the presence of fast switching transients from the inverter. The 1Mbps data rate is adequate for PWM signals and fault feedback. The wide temperature range of -40°C to +125°C suits industrial motor drives. Use it to isolate gate driver signals, current sensing, and encoder feedback. Proper PCB layout with adequate creepage and clearance is essential to maintain isolation ratings.
Recommended
Power Supply Isolation
The ADUM1411ARWZ is used to isolate control signals in power supply designs, such as feedback loops and enable signals. Its high CMTI of 25kV/µs ensures stable operation in the presence of switching noise. The 3750Vrms isolation provides safety isolation between primary and secondary sides. The 1Mbps data rate is sufficient for control signals. The device's low propagation delay helps maintain loop stability. It can replace optocouplers in many designs, offering better performance and reliability. Ensure the isolation barrier is maintained in the PCB layout, and use proper creepage distances for the required isolation level.
Recommended
Medical Equipment Isolation
The ADUM1411ARWZ provides patient isolation in medical devices, meeting safety standards with its 3750Vrms isolation rating. It is used to isolate communication interfaces like UART and SPI between the patient-connected and control sections. The low power consumption and high reliability of iCoupler technology are advantageous for battery-powered devices. The wide temperature range and RoHS compliance make it suitable for medical applications. The 1Mbps data rate is sufficient for most medical data transmission. Ensure the isolation barrier meets the required creepage and clearance for medical safety standards.
Recommended
Communication Interface Isolation
The ADUM1411ARWZ isolates communication interfaces such as RS-232, RS-485, and CAN in networking equipment. Its 3750Vrms isolation prevents ground loops and protects against voltage surges. The 25kV/µs CMTI ensures reliable data transmission in electrically noisy environments. The 1Mbps data rate supports standard communication protocols. The device's small SOIC package saves board space. Use it to isolate transceivers and controllers in industrial networks, building automation, and telecom systems. Proper termination and grounding are essential for optimal performance.

Key Differentiators
- iCoupler technology provides superior reliability over optocouplers (vs Optocoupler-based isolators)
- High CMTI of 25kV/µs (vs ISO7741DW)
- Wide supply voltage range of 2.7V to 5.5V (vs Si8641BB-B-IS1)
Design Notes
Maintain proper creepage and clearance distances between the input and output sides of the ADUM1411ARWZ to achieve the rated 3750Vrms isolation. The SOIC-W package has a minimum creepage of 8mm, which is sufficient for basic insulation. Ensure the PCB layout does not compromise this distance with traces or copper pours. Use a solid ground plane on each side, but do not connect the grounds together except through the isolation barrier.
Bypass each VDD pin with a 0.1µF ceramic capacitor placed as close as possible to the pin. Additionally, a 10µF capacitor can be used for bulk decoupling. The ADUM1411ARWZ draws low quiescent current, but transient currents during switching can cause voltage dips if bypassing is inadequate. Ensure the supply voltage stays within the 2.7V to 5.5V range under all load conditions.
Do not leave the enable pins (VE1, VE2) floating. Tie them to the respective VDD or GND to define the output state. When the enable pin is low, the outputs are high-impedance, which can cause undefined states if not properly handled. Also, ensure the input signals do not exceed the supply voltage to avoid latch-up. Refer to the datasheet for absolute maximum ratings.
