2500Vrms isolation with integrated power — one package replaces two
The ADUM5201ARWZ: It packs two unidirectional isolation channels and an integrated isolated DC-DC converter into a single 16-SOIC package, saving board space versus a separate isolator plus isolated supply. The 2500Vrms isolation rating covers reinforced insulation for industrial and medical power supplies, motor drives, and PLC digital I/O modules. Data rate is 1Mbps, with typical rise/fall times of 2.5ns and propagation delays of 100ns max — fast enough for isolated SPI, UART, or GPIO signals in factory automation and building control.
The 1Mbps data rate, 100ns propagation delay, and 40ns pulse-width distortion suit isolated serial links. The 25kV/µs common-mode transient immunity prevents glitching in motor-drive applications.
Active lifecycle — no rush to stockpile
The ROHS3 compliance is current, with no exemption sunset to track.
Package and temperature — board-fit and environment
It is surface-mount, so standard reflow profiles apply. The magnetic coupling technology means no LED wear-out — the isolation performance does not degrade over time like an optocoupler's.
