ADUM1310ARWZ-RL7 Обзор
A digital isolator is a component that transfers digital signals across an isolation barrier without a direct electrical connection, using capacitive, inductive, or optical coupling. It is essential in systems where safety, noise immunity, or ground potential differences require galvanic isolation. Digital isolators are part of the broader category of isolation components, which also include optocouplers and isolated amplifiers. They are critical in industrial automation, medical equipment, and communication interfaces.
Key features of the ADUM1310ARWZ-RL7 include low power operation: 1.7mA per channel maximum at 5V operation (0-2Mbps) and 4.0mA per channel at 2-10Mbps; at 3V operation, 1.0mA per channel (0-2Mbps) and 2.1mA per channel (2-10Mbps). The device supports three independent isolation channels with a default channel configuration of 2/1 (two forward, one reverse). It also features a refresh mechanism to maintain output states in the absence of input transitions, ensuring reliable operation.
Technically, the ADUM1310 uses monolithic air core transformers and high-speed CMOS to achieve superior performance compared to optocouplers, including higher data rates, lower power consumption, and better timing accuracy. The iCoupler technology eliminates the LED and photodiode aging issues, providing longer operational life and more stable performance over temperature. The device is specified for operation from -40°C to +105°C, making it suitable for industrial environments.
Typical applications include SPI interfaces, RS-232/RS-485 transceivers, isolated data acquisition systems, and general-purpose signal isolation in industrial control, medical monitoring, and power conversion systems. The high CMTI of 25kV/µs ensures reliable operation in noisy environments with fast-switching power stages.
When designing with this device, ensure proper PCB layout with adequate creepage and clearance distances for the required isolation rating. Place decoupling capacitors close to the VDD pins on both sides, and consider the input/output logic levels for voltage translation. The device is RoHS compliant and lead-free.

Заметки по проектированию
For the ADUM1310ARWZ-RL7, ensure proper PCB layout to maintain the specified isolation voltage. Provide adequate creepage and clearance distances between the primary and secondary sides, typically at least 8mm for 3750Vrms reinforced isolation. Use a slot or cutout under the device to increase the creepage path. Place decoupling capacitors (0.1µF) close to VDD1 and VDD2 pins, and connect the exposed pad (if present) to GND1 or GND2 as per datasheet. Avoid routing high-voltage traces under the device.
The ADUM1310ARWZ-RL7 consumes low power, but ensure the supply can handle transient currents during data transitions. At 5V, each channel draws up to 4.0mA at high data rates. Use a low-impedance supply with adequate bypassing. For voltage translation, ensure the logic levels on each side are compatible with the respective supply voltages. The device supports 2.7V to 5.5V on both sides, allowing direct interfacing with 3.3V and 5V logic.
A common pitfall is misinterpreting the channel configuration. The ADUM1310ARWZ-RL7 has a 2/1 configuration (two forward, one reverse). Verify the pinout and signal direction before layout. Also, do not exceed the absolute maximum ratings, especially the isolation voltage and supply voltage. Ensure the input signals are within the specified common-mode voltage range. For unconnected inputs, tie them to GND or VDD to avoid undefined states, as the device has a refresh mechanism but may still be sensitive to floating inputs.
