Package and mounting
The ADUM1300ARWZ: All three channels run from side 1 to side 2 (3/0 input mapping), so it is a straight-through isolator for signals that never need to reverse direction — think SPI clock, data, and chip-select lines leaving a controller. The data rate caps at 1Mbps, which suits slow serial buses, GPIO isolation, or status-feedback loops in motor drives and industrial controls. Supply range spans 2.7V to 5.5V, letting it bridge a 3.3V MCU domain to a 5V power-stage side without a level shifter.
Data rate is 1Mbps. The ADUM1300BRWZ offers 10Mbps with 50ns propagation delay.
Common-mode transient immunity and industrial noise
Minimum common-mode transient immunity is 25kV/µs, a figure that keeps the output from glitching when fast-switching IGBTs or MOSFETs slam the ground reference on one side of the barrier. In a motor-drive or inverter environment, that spec is what prevents false triggers on the controller-side logic. Propagation delay maxes at 100ns each way, symmetrical, so the pulse-width distortion stays under 40ns — acceptable for most 1Mbps signalling but worth checking if your protocol has tight bit-time margins.
