Three-channel magnetic isolator for noisy environments
The 10 Mbps data rate with 50 ns max propagation delay keeps timing closure straightforward for most serial peripherals, while the 25 kV/µs minimum common-mode transient immunity (CMTI) ensures data integrity when the isolation barrier sees fast voltage transients from switching power stages.
Supply range and logic-level compatibility
If your design runs a 3.3 V MCU on one side and a 5 V sensor or actuator on the other, the ADUM1300BRWZ handles it directly — just power each side from its respective rail. The unidirectional channel arrangement (three inputs on side 1, zero on side 2) is set for data flowing from the controller to the isolated peripheral; for bidirectional buses like RS-485 you would need a different channel configuration.
Package and rework considerations
The wide body gives good clearance for probe access and inspection. No exposed thermal pad means you do not need a via stitch under the part, but the wide-body SOIC still benefits from a solid ground plane pour on the PCB for noise coupling control across the barrier.
The 105°C ceiling gives headroom above the 85°C typical for commercial-grade parts, so it can live next to a warm power supply or motor driver without derating concerns.
