The ADUM1300CRWZ is a three-channel, unidirectional digital isolator from ADI's iCoupler family, using magnetic coupling to pass signals across a 2500 Vrms isolation barrier. Its 90 Mbps data rate supports high-speed interfaces like SPI, CAN, and RS-485 without adding timing margin headaches — the 32 ns propagation delay and 2 ns pulse-width distortion keep skew tight enough for most synchronous serial links. The 25 kV/µs common-mode transient immunity means it holds data integrity in motor-drive or inverter environments where fast switching edges couple across the barrier.
Channel direction and package
All three channels are oriented input-to-output (Side 1 / Side 2 = 3/0), so this variant is strictly for isolating downstream signals from a controller. The 16-SOIC wide-body (7.50 mm width) footprint is common for multi-channel isolators and gives decent creepage for basic 2500 Vrms applications. Supplied in tube — if your pick-and-place prefers tape-and-reel, check the ADUM1300CRWZ-RL sibling.
