Product details

Overview

ADUM263N0BRIZ-RL from Analog Devices is a 6-channel, 5.0 kV_RMS 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 ADUM263N0BRIZ-RL datasheet, ADUM263N0BRIZ-RL pinout, ADUM263N0BRIZ-RL application, or ADUM263N0BRIZ-RL equivalent, key selection criteria include reinforced isolation rating (5.0 kV_RMS, VIORM = 849 V_PEAK), 1.7–5.5 V dual-supply operation, AEC-Q100 qualification, and channel-specific fail-safe behavior under undervoltage conditions.

Technical Context

The ADUM263N0BRIZ-RL implements six independent unidirectional CMOS-isolated channels using monolithic air-core transformers, supporting asymmetric supply configurations (e.g., 1.8 V side 1 / 3.3 V side 2) and ensuring DC-correct output states without input transitions. Its architecture guarantees tight channel-to-channel propagation delay matching (≤4.0 ns codirectional skew).

It features dual UVLO thresholds (1.6 V/1.5 V hysteresis), robust common-mode transient immunity (100 kV/µs), and compliance with reinforced insulation standards including DIN EN IEC 60747-17 (VDE 0884-17) and IEC/CSA 60601-1 (2 MOPP). The device operates across −40°C to +125°C with thermal derating per safety limits.

The following parts are listed as comparable options for similar digital isolator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SI8660BB-B-IS	6-channel, 5.0 kV_RMS, 150 Mbps, but uses capacitive isolation and lacks AEC-Q100 qualification	Not suitable for automotive safety-critical systems requiring 2 MOPP or extended temperature validation	Select ADUM263N0BRIZ-RL when medical or automotive qualification, transformer-based reliability, or higher CMTI is required

FAQ

What is the fail-safe behavior of ADUM263N0BRIZ-RL?

The ADUM263N0BRIZ-RL is the N0 variant, meaning its outputs default to logic low when the input-side supply (VDD1) falls below the UVLO threshold (1.5 V). This behavior prevents undefined states in critical control paths such as gate driver enables or safety interlocks during brownout conditions. The output remains low until VDD1 rises above 1.6 V, at which point normal signal transmission resumes. This is confirmed in Table 1 and the General Description section of the Rev. C datasheet.

Does ADUM263N0BRIZ-RL support 1.8 V operation on both sides?

Yes, ADUM263N0BRIZ-RL operates with supply voltages from 1.7 V to 5.5 V on both VDD1 and VDD2 independently. Electrical Characteristics tables for 1.8 V operation (Table 7) confirm propagation delay ≤15 ns, data rate up to 150 Mbps, and quiescent current of 2.6 mA (side 1) / 2.5 mA (side 2) under N0 configuration. This enables direct interfacing with ultra-low-voltage MCUs and sensors without level-shifting circuitry.

What safety certifications apply specifically to ADUM263N0BRIZ-RL?

ADUM263N0BRIZ-RL carries UL 1577 (5000 V_RMS), DIN EN IEC 60747-17 (VDE 0884-17) reinforced (849 V_PEAK), IEC/CSA 60601-1 (2 MOPP), IEC/CSA 62368-1, and CQC GB 4943.1 approvals. These are verified per Table 11 and the Regulatory Information section. The "*" marking on the package denotes VDE 0884-17 compliance, and the device is AEC-Q100 qualified for automotive use.

How does ADUM263N0BRIZ-RL achieve DC correctness without input toggling?

Unlike optocouplers, ADUM263N0BRIZ-RL uses on-chip refresh circuitry that periodically samples the input state-even during static conditions-to maintain accurate output logic levels. This ensures outputs remain valid (high/low) regardless of input signal activity, which is essential for enable, reset, or watchdog signals in safety-critical systems. This functionality is explicitly described in the General Description section of the datasheet.

What is the maximum continuous working voltage for ADUM263N0BRIZ-RL?

The maximum continuous working voltage (VIOWM) for ADUM263N0BRIZ-RL is 600 V_RMS, as specified in Table 12 under DIN EN IEC 60747-17. This value defines the highest RMS voltage the isolation barrier can sustain continuously under normal operating conditions and pollution degree 2. It is distinct from the 5.0 kV_RMS 1-minute dielectric test voltage and the 8000 V_PEAK transient rating.
