This makes it a space- and BOM-efficient choice for designs that need both signal isolation and a small amount of isolated power for a sensor, ADC, or transceiver on the secondary side. The 25 Mbps data rate places this part in the mid-speed tier of the ADUM5211 family. It handles SPI at 20 MHz, UART at standard baud rates, and most industrial fieldbus interfaces (RS-485, CAN at 1 Mbps, Profibus up to 12 Mbps) with margin. The 35 ns max propagation delay and 3 ns max pulse-width distortion keep timing jitter low enough for clocked serial links. If your application needs 100 Mbps throughput — for example, a high-speed ADC data stream or a parallel bus — the ADUM5211CRSZ is the faster sibling at 100 Mbps, with a tighter 24 ns propagation delay. The trade-off is a slightly higher supply current at speed; the 25 Mbps variant draws less quiescent power when the bus is idle. ## Isolated power: what the integrated converter covers The integrated isoPower DC-DC converter provides up to 50 mW of isolated output power — enough to bias a small op-amp, a single RS-485 transceiver, or a low-power sensor. The output is not regulated to a tight tolerance; expect ripple in the tens of millivolts at light load. For noise-sensitive analog circuits, a post-regulator LDO on the isolated rail is recommended. The 2500 Vrms isolation rating is basic isolation per UL 1577, suitable for industrial equipment, medical non-patient-contact, and general-purpose galvanic isolation. The common-mode transient immunity of 25 kV/µs ensures the data path stays clean during fast switching events on the primary side, such as a motor-drive PWM edge. ## Lifecycle and sourcing ROHS3 compliant. For dual-sourcing flexibility, the ADUM5211CRSZ is a pin-compatible 100 Mbps variant in the same package — a drop-in replacement if the design can tolerate the higher data rate and slightly higher supply current.","metaTitle":"ADUM5211BRSZ Digital Isolator, 25Mbps, 2500Vrms, IsoPower","metaDescription":"ADUM5211BRSZ general-purpose 2-channel digital isolator with integrated isolated power. 25 Mbps data rate, 2500 Vrms isolation, -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":"25Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"Yes","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"1/1","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"20-SSOP","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"35ns, 35ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.78","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.78000","currency":"USD"},{"qty":10,"price":"$8.83800","currency":"USD"},{"qty":25,"price":"$8.42680","currency":"USD"},{"qty":100,"price":"$7.31700","currency":"USD"},{"qty":250,"price":"$6.98820","currency":"USD"},{"qty":500,"price":"$6.37158","currency":"USD"},{"qty":1000,"price":"$5.54944","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8c89dbecced6d76d11bd0c1eddddc4b6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ADUM5211BRSZ provide isolated power?","answer":"Yes, it integrates an isoPower DC-DC converter that generates an isolated output voltage from the input-side supply, eliminating the need for a separate isolated power module."},{"question":"How does ADUM5211BRSZ compare to ADUM5211CRSZ?","answer":"The ADUM5211CRSZ is a faster variant with a 100 Mbps data rate and 24 ns propagation delay, versus 25 Mbps and 35 ns for the BRSZ.
