ADUM1410ARWZ 개요
Digital isolators are components that transfer digital signals across an isolation barrier without a direct electrical connection, using capacitive, inductive, or optical coupling. They are essential in systems where safety, noise immunity, or ground potential differences require galvanic isolation. The ADUM1410ARWZ uses monolithic air core transformers and high-speed CMOS, offering superior performance compared to optocouplers, including higher data rates, lower power consumption, and better reliability.
Key features include low power operation: 1.3mA per channel maximum at 5V operation (0-2Mbps) and 0.8mA per channel at 3V operation. The device supports 3V and 5V supply levels, making it versatile for mixed-voltage systems. With 4 channels, it can isolate multiple signal lines in a single package, reducing board space and component count.
The ADUM1410ARWZ is designed for general-purpose isolation, with a wide operating temperature range of -40°C to +125°C. Its 25kV/µs CMTI ensures reliable operation in noisy industrial environments, preventing data corruption from fast transients. The device is RoHS compliant and lead-free, meeting modern environmental standards.
Typical applications include industrial fieldbus communication, isolated SPI/UART interfaces, motor control feedback, and power supply monitoring. The high isolation voltage and robust CMTI make it suitable for applications requiring safety isolation, such as medical equipment and grid infrastructure.
When designing with the ADUM1410ARWZ, ensure proper PCB layout with adequate creepage and clearance distances to maintain isolation ratings. Bypass capacitors should be placed close to the VDD pins to minimize noise. The device does not require external components for isolation, simplifying design.

설계 노트
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.
