Typical Applications
ADUM1300ARWZ is suitable for 6 applications: Industrial Fieldbus Communication, Motor Control, Power Inverters, Isolated SPI/UART Interface, Medical Equipment, Data Acquisition Systems.
Industrial Fieldbus Communication
The ADUM1300ARWZ provides galvanic isolation for fieldbus interfaces like RS-485 and CAN, protecting controllers from ground loops and voltage transients. Its 2500Vrms isolation and 25kV/Β΅s CMTI ensure reliable data transmission in noisy industrial environments. The 1Mbps data rate is adequate for most fieldbus protocols, and the 3.0V to 5.5V supply range allows direct interface with common logic levels. When used with a transceiver like the ADM2483, it enables robust isolated communication links.
Recommended
Motor Control
In motor control systems, the ADUM1300ARWZ isolates gate drive signals and feedback from the microcontroller. Its high CMTI of 25kV/Β΅s prevents false triggering due to fast switching transients in the power stage. The 2500Vrms isolation protects low-voltage control circuitry from high-voltage bus voltages. The device's 1Mbps data rate is sufficient for PWM signals up to several hundred kHz. Proper PCB layout with adequate creepage is essential to maintain isolation integrity.
Recommended
Power Inverters
The ADUM1300ARWZ is used in power inverters to isolate control signals from high-voltage power stages. Its 2500Vrms isolation rating meets safety requirements for many inverter designs. The high CMTI ensures reliable operation in the presence of fast voltage transients from switching IGBTs or MOSFETs. The device's low power consumption helps maintain efficiency in the control circuitry. It is suitable for solar inverters, UPS systems, and variable frequency drives.
Recommended
Isolated SPI/UART Interface
The ADUM1300ARWZ provides isolation for SPI and UART communication between systems with different ground potentials. Its three channels can be configured to isolate clock, data, and control signals. The 1Mbps data rate supports standard SPI speeds up to 1MHz and UART baud rates up to 1Mbps. The device's low propagation delay ensures minimal timing skew in synchronous protocols. It is ideal for isolated sensor interfaces and data acquisition systems.
Recommended
Medical Equipment
In medical devices, the ADUM1300ARWZ provides patient isolation, protecting users from electric shock. Its 2500Vrms isolation rating meets safety standards for many medical applications. The device's low power consumption and small footprint make it suitable for portable medical devices. The high CMTI ensures reliable operation in environments with electromagnetic interference. It is used in patient monitors, infusion pumps, and diagnostic equipment.
Recommended
Data Acquisition Systems
The ADUM1300ARWZ isolates digital signals in data acquisition systems, preventing ground loops and noise from corrupting measurements. Its 2500Vrms isolation protects sensitive analog front-ends from digital noise. The 1Mbps data rate is sufficient for most ADC and DAC control signals. The device's low power consumption is beneficial for battery-powered systems. It is commonly used in industrial data loggers and test equipment.

Design Notes
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 0.1Β΅F ceramic capacitors placed as close as possible to the pins. Additionally, use a 10Β΅F 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.
