Its 1 Mbps data rate is the practical ceiling for isolating slower serial buses — SPI at a few MHz, UART at 115.2 kbaud or 1 Mbaud, and general-purpose GPIO isolation where the signal edges don't need sub-microsecond fidelity. The 2/2 channel split means two channels run from Side 1 to Side 2, two from Side 2 to Side 1, which maps cleanly to a half-duplex SPI bus (MISO, MOSI, plus two control lines) or a pair of bidirectional control signals. ## 2500 Vrms isolation and 25 kV/µs CMTI — where it goes Rated for 2500 Vrms isolation, this part handles the basic reinforced isolation barrier required in industrial sensors, PLC I/O modules, and medical equipment where the safety standard demands galvanic separation between the human interface and the high-voltage side. The 25 kV/µs common-mode transient immunity is the spec that matters when the isolator sits between a microcontroller and a motor-drive power stage — fast IGBT or SiC switching edges can couple several kilovolts per microsecond across the barrier, and a part with lower CMTI would glitch or latch. The 100 ns max propagation delay and 40 ns max pulse-width distortion keep the timing budget predictable for edge-triggered protocols. The 16-SOIC wide-body package is the standard footprint for 2500 Vrms-rated isolators, so the board layout transfers across multiple iCoupler channel-count variants.","metaTitle":"ADUM1402ARWZ-RL iCoupler Digital Isolator, 1 Mbps, 2500 Vrms","metaDescription":"ADI ADUM1402ARWZ-RL iCoupler 4-channel digital isolator, 1 Mbps data rate, 2500 Vrms isolation, 16-SOIC, -40°C to 105°C.
