Typical Applications
ADUM1300ARWZ-RL7 is suitable for 6 applications: Industrial Fieldbus Communication, Isolated SPI/UART Interface, Motor Control and Inverter Gate Drive, Medical Equipment Isolation, Isolated Power Supply Feedback, Data Acquisition and Instrumentation.
Industrial Fieldbus Communication
The ADUM1300ARWZ-RL7 provides galvanic isolation for industrial fieldbus interfaces such as RS-485, CAN, and PROFIBUS. Its 2500 Vrms isolation and 25 kV/Β΅s CMTI ensure reliable data transmission in noisy factory environments. The 1 Mbps data rate is sufficient for most fieldbus protocols, and the wide supply range (2.7 V to 5.5 V) allows interfacing with different logic levels. By isolating the transceiver from the controller, ground loops and voltage spikes are prevented, enhancing system safety and reliability.
Recommended
Isolated SPI/UART Interface
The ADUM1300ARWZ-RL7 is ideal for isolating SPI or UART communication between microcontrollers and peripheral devices. With three channels, it can isolate the clock, data, and chip-select lines, providing complete galvanic isolation. The 1 Mbps data rate supports standard SPI speeds, and the low propagation delay ensures minimal signal skew. This application is common in motor control, data acquisition, and power conversion systems where the controller and power stage must be electrically isolated.
Recommended
Motor Control and Inverter Gate Drive
In motor control and inverter applications, the ADUM1300ARWZ-RL7 isolates the low-voltage control circuitry from the high-voltage power stage. Its high CMTI (25 kV/Β΅s) ensures that fast switching transients do not corrupt the control signals. The 2500 Vrms isolation rating provides adequate protection for 230V AC or 400V DC systems. The device's wide operating temperature range (-40Β°C to +105Β°C) makes it suitable for industrial drives and HVAC systems.
Recommended
Medical Equipment Isolation
The ADUM1300ARWZ-RL7 is used in medical devices to provide patient isolation, ensuring safety from electric shock. Its 2500 Vrms isolation rating meets the requirements for many medical standards. The device's low power consumption and high reliability make it suitable for battery-powered and portable medical equipment. It is commonly used in patient monitoring systems, diagnostic devices, and infusion pumps to isolate sensor signals from the main processor.
Recommended
Isolated Power Supply Feedback
The ADUM1300ARWZ-RL7 can be used to isolate the feedback signal in switched-mode power supplies. By isolating the error amplifier output from the primary-side controller, the power supply can achieve better regulation and safety. The 1 Mbps data rate is sufficient for feedback signals, and the high CMTI ensures stable operation under load transients. This application is common in AC-DC converters, DC-DC converters, and battery chargers.
Recommended
Data Acquisition and Instrumentation
In data acquisition systems, the ADUM1300ARWZ-RL7 isolates the analog front-end from the digital processing unit, preventing ground loops and noise. Its 2500 Vrms isolation rating protects sensitive measurement circuits from high common-mode voltages. The device's low propagation delay and high CMTI ensure accurate signal transmission. It is used in applications such as industrial process control, laboratory instruments, and environmental monitoring systems.

Key Differentiators
- iCoupler technology provides superior reliability compared to optocouplers (vs Optocoupler-based isolators)
- High CMTI of 25 kV/Β΅s (vs ISO7131)
- Wide supply voltage range (2.7 V to 5.5 V) (vs SI8610)
Design Notes
For optimal performance, place bypass capacitors (0.1 Β΅F) close to the VDD1 and VDD2 pins on both sides of the isolator. Use a solid ground plane under the device to minimize noise. Ensure adequate creepage and clearance distances on the PCB to maintain the 2500 Vrms isolation rating.
Keep the isolation barrier clear of any copper traces or components to avoid reducing the isolation voltage. Route high-voltage and low-voltage traces on opposite sides of the PCB, and maintain a minimum distance of 8 mm between them for 2500 Vrms isolation.
Do not exceed the absolute maximum supply voltage of 7 V on either side. Ensure that the input signals do not exceed the supply voltage. Also, avoid floating unused input pins; tie them to GND or VDD as appropriate to prevent undefined states.
Compliance Information
