It delivers 3000Vrms isolation in a standard 8-SOIC footprint, with a 2Mbps data rate and 25kV/µs common-mode transient immunity. ## 2Mbps data rate and 180ns propagation delay — the timing budget The 2Mbps data rate and 180ns max propagation delay set the timing ceiling. For a 1 MHz SPI clock, the 180ns one-way delay consumes about 18% of a half-cycle — workable with careful setup/hold margin on the far side. The 8ns max pulse-width distortion keeps the duty cycle within 1.6% at 1 MHz, so the isolator won't skew a PWM signal enough to upset a motor controller. Rise and fall times are 2ns typical, which means the output edges are clean enough for most digital inputs without extra schmitt-trigger buffering. ## 25kV/µs CMTI — why it matters for motor drives and inverters Common-mode transient immunity of 25kV/µs is the spec that keeps data integrity when a high-side IGBT switches 600V in a few nanoseconds. If the CMTI is too low, the isolator's output toggles falsely, corrupting the gate-drive command. At 25kV/µs this part handles the dV/dt from a typical 1200V Si IGBT module with margin. For SiC or GaN stages with faster switching edges, you'd want a higher-rated isolator — but for most industrial inverter and servo-drive designs, 25kV/µs is sufficient.","metaTitle":"ADUM1241ARZ-RL7 iCoupler Digital Isolator, 3000Vrms, 2Mbps","metaDescription":"ADI ADUM1241ARZ-RL7 digital isolator: 2-channel unidirectional, 3000Vrms isolation, 2Mbps data rate, 25kV/µs CMTI, -40°C to 125°C, SOIC-8.

Both sides run from the same supply range, so a 3.3V rail on side 1 and side 2 works without level shifting. The unidirectional channel configuration (1 input on side 1, 1 input on side 2) means each channel passes data in one direction only — plan the signal flow accordingly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM1241ARZ-RL7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM1241ARZ-RL7 when reusing this data.
