Product details

Automotive-grade 150 Mbps isolation with a 3/1 channel split

The ADUM141E1WBRWZ-RL is an automotive-qualified, 4-channel digital isolator from Analog Devices' iCoupler family, built around magnetic coupling. It pushes 150 Mbps per channel with a 13 ns propagation delay and 3 ns pulse-width distortion — fast enough for isolated SPI, UART, and CAN FD interfaces without adding timing headaches. The 3/1 input-side split (three channels forward, one reverse) is the specific configuration that fits a standard SPI bus: MOSI, MISO, SCLK, and a chip-select or interrupt line going the other way. Rated for 3750 Vrms isolation with a minimum common-mode transient immunity of 75 kV/µs, this part handles the noise environment of motor-drive inverters, on-board chargers, and battery-management systems where fast-switching SiC or GaN stages try to couple common-mode spikes across the isolation barrier.

Frequently asked questions

Is the ADUM141E1WBRWZ-RL automotive qualified?

Yes, the "W" in the order code designates an automotive-grade variant.

What is the closest functional second-source for ADUM141E1WBRWZ-RL?

The ADUM140D1BRZ-RL7 is a pin-compatible sibling in the same iCoupler family with the same 150 Mbps data rate, 2.5 ns rise/fall times, and 13 ns propagation delay. The key difference is the channel direction: the ADUM140D1BRZ-RL7 has all four channels in the forward direction (4/0 split), while the ADUM141E1WBRWZ-RL uses a 3/1 split with one reverse channel. If your application needs a reverse-direction signal, the ADUM140D1BRZ-RL7 will not work without an external level shifter or a second isolator.
