Its headline rating is 5000Vrms isolation — that's the reinforced-grade figure that lets it sit across a safety barrier in industrial PSUs, motor drives, and medical equipment where an optocoupler would normally go. The 1Mbps data rate is the slowest speed grade in the ADuM2401 family, so if your SPI or UART bus runs above that, step up to the BRZ (25 Mbps) or CRZ (90 Mbps) variants. Supply range spans 2.7V to 5.5V, covering both 3.3V and 5V domains on either side. ## 25 kV/µs CMTI — the spec that keeps data clean in a switching environment Common-mode transient immunity is rated at 25kV/µs minimum. In a motor-drive or inverter stage where the ground plane jumps several hundred volts in a few nanoseconds, that CMTI floor prevents bit errors on the isolated data path. Propagation delay is 100ns max each way, with pulse-width distortion held to 40ns max — tight enough for most industrial fieldbus and GPIO isolation. Rise and fall times are 2.5ns typical, so the output edges are clean without excessive ringing. ## Temperature grade and package — industrial environments only That covers factory-floor cabinets, outdoor telecom shelters, and engine-bay-adjacent electronics, but not full automotive under-hood (125°C+). The package is a 16-pin SOIC wide-body (7.50mm width) — the same footprint used across the ADuM2401 family, so a speed-grade swap (ARIZ to BRZ) is a direct BOM change without a board spin. Surface-mount only. ## Channel assignment — 3 inputs on side 1, 1 input on side 2 The channel direction is fixed: three channels run from side 1 to side 2, one channel runs from side 2 to side 1. That 3/1 split suits applications like an SPI bus isolation (SCK, MOSI, CS forward; MISO return) or a few discrete GPIO signals with one feedback line. No isolated power output — you supply both sides independently. ADI lists the ADUM2401ARIZ as Active.","metaTitle":"ADUM2401ARIZ Digital Isolator, 5000Vrms, 1Mbps, 16-SOIC","metaDescription":"ADUM2401ARIZ iCoupler 4-channel digital isolator, 5000Vrms isolation, 1Mbps data rate, -40°C to 105°C, 16-SOIC.
