The 2500Vrms isolation rating covers basic isolation requirements for industrial sensors, motor drives, and medical equipment where the barrier must withstand continuous voltage stress. With a 1Mbps data rate and 100ns max propagation delay, it handles moderate-speed control and status signals without timing margin issues. ## 25kV/µs CMTI — keeps data clean in noisy environments Common-mode transient immunity of 25kV/µs (minimum) means the isolator rejects fast voltage spikes between the two grounds — essential in motor-drive inverters, industrial power stages, and any system with high dV/dt switching. The 2.5ns typical rise/fall time and 40ns max pulse-width distortion preserve signal integrity for pulse trains and edge-triggered inputs. Supply voltage accepts either 3V to 3.6V or 4.5V to 5.5V, allowing the same part to bridge a 3.3V logic domain to a 5V peripheral side without a level shifter. ## 20-SSOP package and operating range Housed in a 20-SSOP (5.30mm width) surface-mount package, the ADUM3470ARSZ fits standard PCB layouts without requiring a dedicated isolation footprint.","metaTitle":"ADUM3470ARSZ Digital Isolator, 2500Vrms, 4-Ch, 20-SSOP","metaDescription":"ADUM3470ARSZ iCoupler 4-channel unidirectional digital isolator, 2500Vrms isolation, 1Mbps data rate, 25kV/µs CMTI, -40°C to 105°C.

The key difference is input-side distribution — ADUM3402 has a 2/2 split (two inputs on side 1, two on side 2), whereas ADUM3470 has all four inputs on side 1. If your design requires bidirectional isolation or return signals, the ADUM3402 is the better fit; for a pure one-way bank, the ADUM3470 is the simpler choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM3470ARSZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM3470ARSZ when reusing this data.
