The 18ns max propagation delay (tpLH/tpHL) and 3ns typical rise/fall times mean you budget roughly 36 ns round-trip for a feedback loop; the 2ns max pulse-width distortion keeps duty-cycle errors under half a percent at 10 MHz, which matters for PWM duty-cycle accuracy in motor drives. ## Common-mode transient immunity — the motor-drive spec Rated at 25kV/µs minimum CMTI, this isolator holds its output state through the fast voltage swings on a 600V or 1200V inverter phase node. If you are isolating a gate-driver or current-sense signal on a variable-frequency drive, that 25kV/µs figure is the one that keeps the output from glitching when the IGBT switches. ## Supply-voltage range and level shifting With a supply range of 3V to 5.5V on both sides (single supply, same Vdd for input and output), the ADUM3100ARZ-RL7 can act as a 5V-to-3.3V or 3.3V-to-5V level shifter as long as both sides share the same supply rail. For true dual-supply level translation where input and output run at different voltages, you would need a part like the ADuM120x with separate Vdd pins. The 1/0 input-to-output channel count means signal flows in one direction only — this is a one-way isolator, not a bidirectional buffer. ## Package and footprint reality Housed in the standard 8-SOIC narrow-body (3.90mm width), the ADUM3100ARZ-RL7 shares the same land pattern as countless other SOIC-8 isolators and op-amps. Surface-mount only — no through-hole option. The 8-SOIC package has no exposed pad, so all thermal dissipation goes through the leads; at 25Mbps continuous the die stays cool, but if you are running near the full data rate at 105°C ambient, keep the airflow moving. ## Lifecycle and supply posture If you are filling a BOM line today, this part is in the active channel with no last-time-buy clock running.","metaTitle":"ADUM3100ARZ-RL7 Digital Isolator, 25Mbps, 2500Vrms, SOIC-8","metaDescription":"ADI ADUM3100ARZ-RL7 iCoupler digital isolator: 1-channel unidirectional, 25Mbps data rate, 2500Vrms isolation, 3-5.5V supply, -40 to 105°C.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"iCoupler®","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"25Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"1","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"1/0","Rise / Fall Time (Typ)":"3ns, 3ns","Supplier Device Package":"8-SOIC","Pulse Width Distortion (Max)":"2ns","Propagation Delay tpLH / tpHL (Max)":"18ns, 18ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.44","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.44000","currency":"USD"},{"qty":10,"price":"$3.99000","currency":"USD"},{"qty":25,"price":"$3.77240","currency":"USD"},{"qty":100,"price":"$3.26940","currency":"USD"},{"qty":250,"price":"$3.10172","currency":"USD"},{"qty":500,"price":"$2.78316","currency":"USD"},{"qty":1000,"price":"$2.34724","currency":"USD"},{"qty":2000,"price":"$2.22988","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADUM3100.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between ADUM3100 and ADUM3200?","answer":"The ADUM3200 is a 2-channel isolator (both channels forward direction) versus the single-channel ADUM3100. Both run at 25Mbps and share the same 2500Vrms isolation rating and SOIC-8 footprint. The ADUM3200 is the part to pick when you need two isolated signal paths in one package."},{"question":"Can ADUM3100ARZ-RL7 be used for 5V to 3.3V level shifting?","answer":"Yes, but only when both sides share the same supply voltage. The ADUM3100ARZ-RL7 has a single Vdd pin that powers both the input and output side. If your design needs separate 5V and 3.3V supplies for level translation, you need a dual-supply isolator such as the ADuM120x family."},{"question":"Is ADUM3100ARZ-RL7 suitable for CAN bus isolation?","answer":"The ADUM3100ARZ-RL7 is a general-purpose digital isolator with 25Mbps data rate and 2500Vrms isolation. It can isolate a CAN transceiver's digital TX and RX signals if you use two channels (one per direction), but a dedicated CAN isolator like the ADM3053 integrates the transceiver. For the isolation barrier itself, the 25kV/µs CMTI and 25Mbps rate are adequate for CAN at 1Mbps."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM3100ARZ-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/ADUM3100ARZ-RL7 when reusing this data.
