3750 Vrms isolation in a 16-SOIC — what it buys the BOM
The ADUM131E0BRWZ-RL is a three-channel digital isolator from Analog Devices' iCoupler series, built on magnetic coupling. It delivers 3750 Vrms isolation in a wide-body 16-SOIC package, with a 150 Mbps data rate and 75 kV/µs common-mode transient immunity. That CMTI number is the standout — it keeps data clean across the barrier in motor drives, inverters, and industrial environments where fast voltage transients would otherwise corrupt the signal.
Three channels, two going one way
Channel configuration is 2 inputs on side 1, 1 input on side 2 — all unidirectional. That matches a typical SPI or UART isolation layout: two lines out (clock, data), one line in (data return). The 13 ns propagation delay and 3 ns pulse-width distortion keep timing tight enough for 150 Mbps operation without needing to re-tune the bus.
Supply range and temperature — industrial and automotive ready
No isolated power on-chip — you supply the secondary-side rail separately, which is the usual approach for multi-rail designs.
