That means it delivers 2500Vrms galvanic isolation for both data and power in a single 8-SOIC package — no separate transformer or external oscillator needed for the secondary-side supply. It is a general-purpose part rated for 1 Mbps data rate with 70 ns max propagation delay and 3 ns pulse-width distortion, so it fits slow control signals (enable lines, fault flags, reset) rather than high-speed serial buses. With a 1 Mbps ceiling and unidirectional channels (two inputs on side 1, zero on side 2), this part is sized for level-triggered or low-frequency signals. It will handle a 100 kHz PWM enable, a relay coil drive signal, or a status LED from the isolated side. It will not pass a 12 MHz SPI clock or a 500 kbps CAN frame cleanly — those need the 100 Mbps ADUM5211CRSZ or similar. The 70 ns propagation delay is consistent in both directions, so timing symmetry is adequate for half-duplex handshake lines. ## Integrated isolated power — what it saves and what it costs This eliminates a separate isolated module or push-pull driver, saving board area and BOM count. The trade-off is output power — the IsoPower stage is designed for low-current loads (tens of mA, not hundreds). If the isolated side needs to power a sensor or an op-amp drawing more than about 50 mA, step up to the ADUM5402CRZ which has four channels and a higher-power converter. ## Lifecycle and compliance For a production BOM that needs dual-sourcing resilience, note that the ADUM5211ARSZ-RL7 is a functional peer with the same isolation voltage and package but a 1 Mbps data rate and different channel direction (1/1 instead of 2/0).","metaTitle":"ADUM5240ARZ Digital Isolator, 2500Vrms, 1Mbps, IsoPower","metaDescription":"ADUM5240ARZ general-purpose digital isolator with integrated isolated DC-DC converter. 2500Vrms isolation, 1Mbps data rate, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"IsoPower®, iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"IsoPower®, iCoupler®","Package":"Tube","Data Rate":"1Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"Yes","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 4.0V, 4.5V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"2/0","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"8-SOIC","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"70ns, 70ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.18","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.18000","currency":"USD"},{"qty":10,"price":"$8.29500","currency":"USD"},{"qty":25,"price":"$7.90920","currency":"USD"},{"qty":100,"price":"$6.86760","currency":"USD"},{"qty":250,"price":"$6.55896","currency":"USD"},{"qty":500,"price":"$5.98020","currency":"USD"},{"qty":1000,"price":"$5.20857","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADUM5240_5241_5242.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ADUM5240ARZ require external components for isolated power?","answer":"The integrated IsoPower DC-DC converter requires only external decoupling capacitors — no separate transformer or oscillator is needed.
