It pushes data at up to 1 Mbps per channel, with 2500 Vrms isolation between the two sides. Propagation delay is 150 ns max, and the pulse-width distortion stays under 40 ns — tight enough for most industrial serial links at this speed. At 1 Mbps this isolator handles UART, SPI (at moderate clock rates), and general-purpose logic isolation. It will not run a full-speed USB or a 10/100 Ethernet PHY interface — those need the 10 Mbps or 150 Mbps variants in the same family. For isolated RS-485 or CAN at typical baud rates (up to 1 Mbps), the 150 ns propagation delay and 10 ns rise/fall times leave enough timing margin. The unidirectional channel arrangement (two inputs on side 1, zero on side 2) means this part is for signals that flow one way only — data from a sensor to a controller, for example. Bidirectional buses like I²C need a different channel configuration or an external direction-control scheme. ## 25 kV/µs CMTI — why it matters in noisy environments Common-mode transient immunity is rated at 25 kV/µs minimum. That is the isolator's ability to reject fast voltage spikes that appear simultaneously on both sides of the isolation barrier — exactly what happens when a motor drive switches or a relay coil de-energises. If the CMTI is too low, those transients couple through the barrier and corrupt the output. For industrial drives, inverters, and any equipment with high dV/dt switching, this spec is the one that keeps the data clean. ## Temperature range and package The 8-pin SOIC package is a standard footprint — no surprises for layout or rework. Surface-mount only; no through-hole option in this variant. ## Lifecycle and compliance No AEC-Q automotive qualification is listed, so for production-vehicle programs a different grade may be needed.","metaTitle":"ADUM1200ARZ Digital Isolator, 2-Ch, 1 Mbps, 2500 Vrms","metaDescription":"ADUM1200ARZ iCoupler 2-channel digital isolator, 1 Mbps data rate, 2500 Vrms isolation, -40 to 105°C.

If you need more speed, that is the natural swap — same package, same pinout, same isolation rating. For a bidirectional channel arrangement, look at the ADUM1201 (same pinout but one channel in each direction)."},{"question":"Can ADUM1200ARZ be used for isolated I²C?","answer":"Not directly. The ADUM1200ARZ has unidirectional channels — both channels go the same direction. I²C is a bidirectional bus requiring data to flow both ways on the same line. You would need a part with at least one channel in each direction (like the ADUM1201) or an external direction-control circuit."},{"question":"Is ADUM1200ARZ RoHS compliant?","answer":"Yes, it is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM1200ARZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM1200ARZ when reusing this data.
