Four-channel isolator with 150 Mbps throughput and 3000 Vrms isolation
The ADUM142E1BRZ-RL7 is a 4-channel, unidirectional digital isolator from Analog Devices' iCoupler series, using magnetic coupling to pass signals across a 3000 Vrms isolation barrier.
75 kV/µs CMTI — built for noisy environments
Common-mode transient immunity is rated at 75 kV/µs minimum, which means the isolator won't glitch when a motor drive or inverter switches a high-voltage rail next to the isolation barrier. Pulse-width distortion is held to 3 ns max, so the duty cycle of a PWM or clock signal stays intact across the barrier.
Channel layout: 2 inputs on side 1, 2 on side 2
The four unidirectional channels are split 2/2 — two inputs on side 1 and two on side 2. That arrangement suits isolating a bidirectional bus like SPI (MISO, MOSI, SCLK, CS) where two signals run each direction. If you need all four channels going the same way, the ADUM140E1BRZ-RL7 (4/0 split) is the sibling to look at.
