Product details
Overview
ADUM261N0BRIZ-RL from Analog Devices is a 6-channel, 5.0 kVRMS reinforced digital isolator using iCoupler® technology, with 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and fail-safe low output configuration. It enables isolated SPI, RS-485, and industrial fieldbus communication in high-noise motor drives and PLC I/O modules.
For engineers reviewing the ADUM261N0BRIZ-RL datasheet, ADUM261N0BRIZ-RL pinout, ADUM261N0BRIZ-RL application, or ADUM261N0BRIZ-RL equivalent, key selection criteria include its 1.7–5.5 V dual-supply operation, 100 kV/µs common-mode transient immunity, AEC-Q100 qualification, and SOIC_IC wide-body package with 8.7 mm creepage/clearance for reinforced insulation compliance.
Technical Context
The ADUM261N0BRIZ-RL implements six independent unidirectional isolation channels using monolithic air-core transformers, supporting asymmetric voltage translation (e.g., 1.8 V side 1 to 5 V side 2). Its fail-safe low logic ensures outputs default to logic low during input-side power loss.
It meets reinforced insulation requirements per DIN EN IEC 60747-17 (VDE 0884-17), UL 1577, and IEC/CSA 60601-1 (2 MOPP), with VIORM = 849 VPEAK, VIOWM = 600 VRMS, and certified working voltage up to 276 VRMS in medical applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 6-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8661ED-B-IS | 6-channel, 5 kVRMS, 150 Mbps, but only 50 kV/µs CMTI and no AEC-Q100 qualification | Limited to industrial automation; not suitable for automotive or medical 2-MOPP designs | Prefer ADUM261N0BRIZ-RL where CMTI >75 kV/µs or automotive qualification is required |
| ISO6760FDWR | 6-channel, 5 kVRMS, 50 Mbps max data rate, lower power, but lacks 1.8 V operation support | Better for low-power, low-speed I/O isolation; insufficient for high-speed SPI or CAN FD timing | Select ADUM261N0BRIZ-RL when ≥100 Mbps data rate and 1.7–5.5 V supply flexibility are mandatory |
Compared with SI8661ED-B-IS and ISO6760FDWR, ADUM261N0BRIZ-RL uniquely combines 150 Mbps speed, 100 kV/µs CMTI, AEC-Q100 qualification, and 1.8 V compatibility-making it the only option for high-reliability automotive SPI isolation and medical-grade high-speed data links.

FAQ
What is the fail-safe behavior of ADUM261N0BRIZ-RL?
The ADUM261N0BRIZ-RL is an N0 variant, meaning its outputs default to logic low when the input-side power supply (VDD1) is absent or below UVLO threshold (1.5 V). This prevents undefined states in safety-critical interfaces like enable lines or fault indicators. The behavior is implemented via internal circuitry and does not require external pull-down resistors.
Does ADUM261N0BRIZ-RL support bidirectional data channels?
No, ADUM261N0BRIZ-RL provides six unidirectional channels only - all inputs (A–F) reside on side 1 (pins 3–8), and corresponding outputs (A–F) reside on side 2 (pins 11–16). For bidirectional isolation (e.g., I²C), a separate part such as ADUM260N0BRIZ-RL must be selected.
What is the maximum working voltage supported by ADUM261N0BRIZ-RL in medical applications?
Per IEC 60601-1 certification, ADUM261N0BRIZ-RL supports a maximum working voltage of 276 VRMS under reinforced insulation (2 MOPP). This rating applies to continuous sinusoidal waveforms at pollution degree 2 and altitudes ≤2000 m, validated per DIN EN IEC 60747-17 test protocols.
Can ADUM261N0BRIZ-RL operate with different supply voltages on each side?
Yes - ADUM261N0BRIZ-RL supports independent VDD1 and VDD2 supplies ranging from 1.7 V to 5.5 V each. This enables true level translation, e.g., 1.8 V MCU SPI interface to 5 V ADC or gate driver, without external level-shifting components or timing penalties.
Is ADUM261N0BRIZ-RL pin-compatible with other ADuM26xN variants?
Yes - all ADuM260N/ADuM261N/ADuM262N/ADuM263N variants share identical 16-lead SOIC_IC (RI-16) packaging and pinout. Only the fail-safe state (N0 = low, N1 = high) and channel directionality differ; no PCB layout change is needed when substituting within the same N-type family.
