ADUM1300ARWZ 概要
Digital isolators are components that transmit digital signals across an isolation barrier, providing galvanic isolation to protect circuits and users from high voltages, ground loops, and noise. They replace optocouplers in many applications, offering higher speed, better reliability, and lower power consumption. The ADUM1300ARWZ is part of the iCoupler family, which uses monolithic transformer technology to achieve superior performance compared to traditional optocouplers.
Key features include three independent isolation channels, a wide supply voltage range of 3.0V to 5.5V, and a maximum data rate of 1Mbps. The device offers 25kV/µs CMTI, ensuring reliable operation in noisy industrial environments. It also features low power consumption, with typical quiescent current of 1.3mA per channel, and operates over a temperature range of -40°C to +105°C.
The ADUM1300ARWZ uses a magnetic coupling architecture, where data is transmitted across a thin isolation barrier using integrated transformers. This approach eliminates the need for LEDs and photodiodes, improving performance and reliability. The device includes a refresh mechanism to maintain output states even when the input is static, ensuring correct operation in all conditions.
Typical applications include industrial fieldbus communication, motor control, power inverters, and isolated SPI/UART interfaces. The high CMTI and 2500Vrms isolation make it suitable for harsh environments where noise and voltage transients are common.
When designing with this device, ensure proper PCB layout with adequate creepage and clearance distances for the isolation rating. Place decoupling capacitors close to the VDD pins and follow the recommended layout guidelines in the datasheet to achieve optimal performance.

設計ノート
For optimal isolation performance, maintain at least 8mm creepage and clearance distances between the primary and secondary sides on the PCB. Place the ADUM1300ARWZ near the board edge to maximize isolation distance. Use a solid ground plane under the device on each side, but do not connect the two ground planes together except through the isolation barrier.
Decouple both VDD1 and VDD2 with 0.1µF ceramic capacitors placed as close as possible to the pins. Additionally, use a 10µF bulk capacitor on each supply if the power source is far away. The ADUM1300ARWZ consumes approximately 1.3mA per channel, so ensure the power supply can handle the total current without significant voltage drop.
Do not exceed the absolute maximum supply voltage of 7V on VDD1 or VDD2. Ensure that the input signals do not exceed the supply voltage by more than 0.5V. When driving the inputs, avoid floating inputs by connecting unused inputs to GND or VDD. The device has a refresh mechanism, but proper termination of unused pins prevents noise-induced errors.
