The ADI ADUM142E0BRZ is a 4-channel, unidirectional digital isolator from the iCoupler family, built around magnetic coupling technology. It delivers 150 Mbps per channel with a typical propagation delay of 13 ns and 3 ns pulse-width distortion — fast enough for SPI, CAN FD, or high-speed UART links without adding timing uncertainty. The 3000 Vrms isolation rating suits industrial motor drives, PLC I/O modules, and medical equipment where a galvanic barrier is required between a controller and a high-voltage domain.
Supply flexibility and logic-level compatibility
The 2/2 input/output split (two channels each direction) fits common sensor-to-controller and controller-to-actuator isolation patterns. Rise and fall times are 2.5 ns typical, keeping signal edges clean at 150 Mbps.
Common-mode transient immunity — the real-world survival spec
With a minimum common-mode transient immunity of 75 kV/µs, this isolator can ride through the fast switching edges of SiC and GaN power stages without corrupting the data. That matters in motor-drive inverter legs, where the floating ground jumps several hundred volts in nanoseconds.
