It provides 3750 Vrms galvanic isolation across a 16-SOIC package, with a unidirectional channel split of two inputs on side 1 and one input on side 2. That 2/1 arrangement suits isolating a bidirectional signal pair plus a separate control line — think SPI chip-select and data lines where the clock and MOSI go one way and MISO returns the other. Data rate is rated at 1 Mbps with a maximum propagation delay of 100 ns in either direction, and pulse-width distortion held to 40 ns max. Common-mode transient immunity is a minimum 25 kV/µs, which means this part can sit on a motor-drive or inverter bus without losing data during fast voltage swings between grounds. ## Active lifecycle — no near-term obsolescence risk ROHS3 compliant, so it clears the usual environmental restrictions for EU and global markets. ## Where the 1 Mbps and 100 ns delay matter At 1 Mbps, the ADUM1311ARWZ is squarely aimed at isolated SPI (up to a few MHz), UART, GPIO, and general-purpose control signals — not high-speed data buses like USB or Ethernet. The 100 ns max propagation delay means you lose about 10% of the bit period at 1 Mbps, so budget that into your timing closure if you are daisy-chaining multiple isolators. The 2.5 ns typical rise/fall time keeps signal edges clean enough for most board-level interconnects without excessive ringing. ## Comparison to the ADUM1310ARWZ — same isolation, different channel map The closest functional peer is the ADUM1310ARWZ. The only parametric difference is the input-side channel allocation: the ADUM1311ARWZ has a 2/1 split (two inputs on side 1, one on side 2), while the ADUM1310ARWZ has all three inputs on side 1 (3/0). If your design needs an isolated bidirectional channel plus a dedicated input, the 2/1 split of the 1311 is the one. If all three signals originate from the same side, the 1310 saves a pin and simplifies routing.","metaTitle":"ADUM1311ARWZ iCoupler Digital Isolator, 3750 Vrms, 1 Mbps","metaDescription":"ADUM1311ARWZ general-purpose digital isolator with 3750 Vrms isolation, 1 Mbps data rate, 3 unidirectional channels (2/1), -40°C to 105°C.
