Typical Applications
ADUM1410ARWZ is suitable for 6 applications: Industrial Fieldbus Communication, Isolated SPI Interface, Motor Control Feedback, Power Supply Monitoring, Medical Equipment Isolation, Isolated UART Communication.
Industrial Fieldbus Communication
The ADUM1410ARWZ provides galvanic isolation for fieldbus interfaces like RS-485, CAN, or PROFIBUS. Its 3750Vrms isolation protects microcontrollers from ground loops and voltage transients in industrial environments. With 4 channels, it can isolate data, clock, and control signals simultaneously. The 1Mbps data rate is sufficient for most fieldbus protocols, and the 25kV/µs CMTI ensures reliable communication in noisy factory floors. The low power consumption (1.3mA per channel) minimizes heat generation in sealed enclosures. The wide operating temperature range (-40°C to +125°C) suits harsh industrial conditions. When used with a transceiver like ADM2483, it enables robust, isolated communication links.
Recommended
Isolated SPI Interface
The ADUM1410ARWZ is ideal for isolating SPI buses between microcontrollers and peripheral devices like ADCs, DACs, or sensors. Its 4 channels can carry SCLK, MOSI, MISO, and CS signals, providing complete isolation for the SPI interface. The 1Mbps data rate supports SPI clock frequencies up to 1MHz, suitable for many precision converters. The 3750Vrms isolation protects sensitive measurement circuits from digital noise and ground potential differences. The low propagation delay and high CMTI ensure data integrity even in electrically noisy environments. The SOIC-16 package is compact, saving board space in multi-channel isolation designs. This application is common in data acquisition systems and industrial instrumentation.
Recommended
Motor Control Feedback
In motor control systems, the ADUM1410ARWZ isolates encoder or resolver feedback signals from the digital controller. The 3750Vrms isolation protects the control electronics from high-voltage transients generated by motor drives. The 4 channels can carry A, B, Z encoder signals and a fault line, providing complete feedback isolation. The 1Mbps data rate is adequate for most encoder interfaces, and the 25kV/µs CMTI ensures reliable operation in the presence of PWM switching noise. The wide temperature range and low power consumption make it suitable for integration into motor drives. The SOIC-16 package allows for compact PCB layouts in space-constrained motor controllers.
Recommended
Power Supply Monitoring
The ADUM1410ARWZ is used to isolate digital monitoring signals from power supply control circuits. It can transmit status signals like power-good, fault, and enable commands across the isolation barrier. The 3750Vrms isolation ensures safe communication between high-voltage power stages and low-voltage control logic. The 4 channels allow multiple monitoring signals to be isolated in a single device, reducing component count. The 1Mbps data rate is sufficient for status and control signals, and the high CMTI prevents false triggering from switching noise. The low power consumption is beneficial in always-on monitoring circuits. This application is common in server power supplies, industrial power converters, and battery management systems.
Recommended
Medical Equipment Isolation
The ADUM1410ARWZ provides galvanic isolation for patient-connected medical devices, ensuring safety and preventing electrical shock. Its 3750Vrms isolation meets basic isolation requirements for medical equipment. The 4 channels can isolate data and control signals between the patient side and the processing side. The low power consumption and wide temperature range make it suitable for portable and wearable medical devices. The high CMTI ensures reliable operation in environments with electromagnetic interference from other medical equipment. The SOIC-16 package is compact, enabling miniaturized designs. This application is critical for ECG monitors, patient monitors, and infusion pumps.
Recommended
Isolated UART Communication
The ADUM1410ARWZ is commonly used to isolate UART signals between microcontrollers and external devices like GPS modules, Bluetooth modules, or industrial sensors. Its 4 channels can carry TX, RX, and control signals (RTS, CTS) across the isolation barrier. The 1Mbps data rate supports standard UART baud rates up to 115200 and beyond. The 3750Vrms isolation protects the main controller from ground loops and noise in remote sensors. The low power consumption is ideal for battery-powered devices. The high CMTI ensures error-free communication in electrically noisy environments. This application is widespread in IoT devices, industrial sensors, and communication gateways.

Design Notes
For optimal isolation performance, maintain at least 8mm creepage and clearance distance between the input and output sides of the ADUM1410ARWZ on the PCB. This ensures the 3750Vrms isolation rating is not compromised by surface contamination or arcing. Place a 0.1µF bypass capacitor close to each VDD pin (VDD1 and VDD2) to decouple high-frequency noise. Use a solid ground plane under the device, but split the ground plane to separate GND1 and GND2 areas to prevent noise coupling across the isolation barrier.
The ADUM1410ARWZ consumes up to 1.3mA per channel at 5V operation, totaling 5.2mA for all four channels. Ensure the power supply can provide sufficient current for both sides (VDD1 and VDD2). Use low-ESR ceramic capacitors (0.1µF) on each supply pin to maintain stable voltage. If the input and output sides have different supply voltages (e.g., 3.3V and 5V), the device supports this as long as both are within the 3V to 5.5V range. Consider using a dedicated LDO for each side to minimize noise.
Do not exceed the absolute maximum ratings, including supply voltage of 7V and isolation voltage of 3750Vrms. Ensure that the input signals do not exceed the supply voltage of the respective side. Avoid floating input pins; connect unused inputs to GND or VDD to prevent undefined states. When routing signals, keep input and output traces separated to maintain isolation. Also, be aware that the ADUM1410ARWZ has a maximum data rate of 1Mbps; for higher speeds, use the ADUM1410BRWZ (10Mbps) or other faster isolators.
