90 Mbps, 2500 Vrms — the isolator for high-speed industrial links
The ADUM1402CRWZ-RL is a 4-channel, unidirectional digital isolator from the iCoupler family, built on magnetic coupling. It delivers a 90 Mbps data rate across a 2500 Vrms isolation barrier, with a 2/2 input-to-output channel split. The 25 kV/µs common-mode transient immunity handles the fast switching edges in motor drives and inverters without corrupting the data.
2/2 channel split — why the direction matters
The ADUM1402CRWZ-RL's 2/2 input/output split is the middle option in the 4-channel iCoupler family. The ADUM1401CRWZ-RL offers a 3/1 split (three channels forward, one reverse), and the ADUM1400CRWZ-RL is all four channels in one direction (4/0). The choice comes down to how many reverse-direction signals your bus needs — the 2/2 part is the right pick for a bidirectional SPI (MISO, MOSI, plus two chip selects or handshake lines) or a full-duplex UART with flow control.
