Two-channel isolator for 1Mbps signal paths
The ADI ADUM1200ARZ-RL7 is a dual-channel, unidirectional digital isolator from the iCoupler family, using magnetic coupling to transfer logic signals across a 2500Vrms isolation barrier.
The 2500Vrms isolation rating is the basic safety isolation level for many industrial and medical applications. It provides galvanic separation between two ground domains, protecting low-voltage logic from transients on the other side. The 25kV/µs common-mode transient immunity means this part can sit on a motor-drive or inverter control board without false-toggling when the power stage switches — a common failure point with optocouplers in those environments.
Unidirectional channels — 2/0 input/output mapping
Both channels run in the same direction (Side 1 to Side 2), with no reverse channel. That means this part is for isolating signals that flow one way — a sensor output to a controller, a control signal to a gate driver, or a relay command. If you need bidirectional isolation (like for a half-duplex RS-485 bus), the ADUM1201 with a 1/1 input split is the sibling to look at.
Active and available through distribution
It is ROHS3 compliant. No LTB or allocation concerns for new designs.
