Product details

150 Mbps, 3750 Vrms — isolation for high-speed interfaces

The ADI ADUM131E1BRWZ-RL is a three-channel, unidirectional digital isolator from the iCoupler family, built with magnetic coupling technology. It delivers 150 Mbps data rate per channel with 2.5 ns typical rise/fall times and 13 ns max propagation delay, making it suitable for isolating high-speed serial interfaces like SPI, CAN FD, or UART without introducing bus-timing margin problems.

That wide supply range simplifies BOM consolidation when bridging different voltage islands on a mixed-signal board. The unidirectional channel configuration — two inputs on side 1, one input on side 2 — fits the typical isolated SPI pattern: MISO, MOSI, and SCLK crossing the barrier in one direction, with a dedicated return channel for data from the peripheral.

Frequently asked questions

Is ADUM131E1BRWZ-RL compatible with 3.3V logic?

Yes.

What is the difference between ADUM131E1BRWZ-RL and the ADUM131E1BRWZ (non-tape)?

All electrical specs — 150 Mbps, 3750 Vrms, 75 kV/µs CMTI — are identical.

How to use ADUM131E1BRWZ-RL for isolated SPI communication?

The 2/1 channel configuration maps directly to a three-wire SPI isolation: two channels on side 1 carry MOSI and SCLK to the peripheral, and the single channel on side 2 returns MISO. The 150 Mbps data rate and 13 ns propagation delay leave ample timing margin for SPI clock rates up to 50 MHz.
