MPN: ADUM141D0BRWZ ✓ Hoạt độngADUM141D0BRWZ Tóm tắt
Digital isolators are components that transfer digital signals across an isolation barrier without a direct electrical connection, using capacitive or magnetic coupling. They are essential in applications where ground potential differences, noise, or safety requirements demand galvanic isolation. The ADUM141D0BRWZ uses iCoupler technology, which combines high-speed CMOS and monolithic air core transformers to achieve superior performance compared to optocouplers, including higher data rates, lower power consumption, and better reliability.
Key features of the ADUM141D0BRWZ include a 3:1 channel configuration (three forward and one reverse channel), a wide supply voltage range of 1.7V to 5.5V, and a high common-mode transient immunity (CMTI) of 75 kV/µs. The device also features a default output state of low (0) on the reverse channel, which is indicated by the '0' in the part number. The propagation delay is typically 7.2 ns, and the device operates over a temperature range of -40°C to +125°C.
The ADUM141D0BRWZ is designed for general-purpose multichannel isolation, SPI/data converter isolation, and industrial field bus isolation. Its high data rate and robust isolation make it ideal for applications such as motor drives, power inverters, and medical equipment where signal integrity and safety are critical. The wide supply voltage range allows operation from both 3.3V and 5V systems, simplifying design.
When designing with the ADUM141D0BRWZ, it is important to ensure proper power supply decoupling with 0.1 µF capacitors close to the VDD1 and VDD2 pins. The input and output sides are isolated, so separate ground planes are required. The device is RoHS compliant and lead-free, meeting environmental standards for modern electronic designs.

Ghi chú thiết kế
Place 0.1 µF decoupling capacitors close to the VDD1 and VDD2 pins, and use a 10 µF bulk capacitor on each supply rail. Ensure that the ground planes on the input and output sides are separated and do not overlap to maintain isolation integrity. The SOIC-W package has a wide body, so ensure adequate creepage distance on the PCB for the 3.75 kV isolation rating.
Keep the isolation barrier clear of any copper traces or components to avoid reducing the isolation voltage. Route high-speed signals with controlled impedance if necessary, and minimize trace lengths to reduce parasitic capacitance. The input and output sides should have separate ground planes connected only through the isolation barrier.
Do not exceed the absolute maximum ratings for supply voltage (7V) or input/output voltage. Ensure that the default output state (low for ADUM141D0BRWZ) is acceptable for your application; if a high default is needed, use the ADUM141D1BRWZ. Also, verify that the data rate and propagation delay meet your timing requirements, especially in high-speed SPI applications.
