Analog Devices Inc. ADUM210N0BRIZ-RL

Overview

ADUM210N0BRIZ-RL from Analog Devices is a single-channel, reinforced-isolation digital isolator based on iCoupler® transformer technology, delivering 5.0 kV_rms withstand voltage, 150 Mbps data rate, and 13 ns max propagation delay at 5 V operation. It supports 1.8 V to 5.5 V dual-supply operation with fail-safe low output state (N0 variant), enabling voltage translation and robust noise immunity in industrial bus interfaces.

For engineers reviewing the ADUM210N0BRIZ-RL datasheet, ADUM210N0BRIZ-RL pinout, ADUM210N0BRIZ-RL application, or ADUM210N0BRIZ-RL equivalent, this page provides verified specifications, SOIC_IC package layout, safety-certified insulation parameters, fail-safe behavior under supply loss, and real-world design implications for high-noise industrial isolation.

Technical Context

The ADUM210N0BRIZ-RL implements on-off keying (OOK) modulation across monolithic air-core transformers, ensuring dc-correct output even during prolonged input inactivity-unlike optocouplers. Its differential architecture enables high common-mode transient immunity (100 kV/µs) and low jitter (380 ps p-p at 5 V).

It features independent 1.7–5.5 V supplies on each side, internal regulators, and dual UVLO thresholds (1.5 V/1.6 V) per side to guarantee safe power-up/power-down sequencing. The N0 variant asserts logic-low output when VDD1 is unpowered, satisfying fail-safe requirements in motor control and PLC I/O modules.

Key Specifications

Pinout & Package

ADUM210N0BRIZ-RL uses an 8-lead, RoHS-compliant SOIC_IC package (width = 5.3 mm, creepage/clearance ≥ 8.3 mm). Input and output sides are galvanically isolated with internal shorting: Pins 1 & 3 share VDD1; Pins 5 & 7 share GND2.

FAQ

What is the fail-safe behavior of ADUM210N0BRIZ-RL when the input-side supply is removed?

ADUM210N0BRIZ-RL is the N0 variant, meaning its output defaults to logic low when VDD1 is unpowered or VI is floating. This behavior is guaranteed by internal circuitry and documented in the truth table (Table 16). It ensures safe shutdown in motor control or safety interlock applications where unintended high-level outputs could cause hazardous conditions. The output remains low regardless of VDD2 state, provided VDD1 is absent.

Does ADUM210N0BRIZ-RL support level translation between 1.8 V and 5 V logic domains?

Yes, ADUM210N0BRIZ-RL supports independent 1.8 V to 5.5 V supplies on each side (VDD1 and VDD2), enabling seamless level translation. For example, it can accept a 1.8 V CMOS input referenced to GND1 and drive a 5 V CMOS output referenced to GND2. Input thresholds scale with VDD1 (VIH = 0.7×VDD1), and output drive strength adapts to VDD2 - all without external components. This is confirmed in Tables 1–7 and the General Description section.

What safety certifications apply to ADUM210N0BRIZ-RL?

ADUM210N0BRIZ-RL holds UL 1577 (5000 V_rms), IEC/EN/CSA 60950-1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, and DIN EN IEC 60747-17 (VDE 0884-17) certifications. Its VIORM = 849 V_peak and reinforced insulation rating satisfy medical and industrial safety standards. Certification details are listed in Table 11 and the Regulatory Information section of the datasheet.

Can ADUM210N0BRIZ-RL operate reliably in environments with high common-mode transients?

Yes, ADUM210N0BRIZ-RL achieves 100 kV/µs common-mode transient immunity (CMTI) - validated per test conditions in Table 1 - making it suitable for noisy environments like motor drives and industrial inverters. Its transformer-based iCoupler architecture inherently rejects fast dv/dt noise across the isolation barrier, unlike capacitive isolators that may exhibit higher susceptibility. This value is measured at VCM = 1000 V with 800 V transient magnitude.

What is the maximum continuous working voltage supported by ADUM210N0BRIZ-RL?

ADUM210N0BRIZ-RL supports a maximum continuous working voltage of 849 V_peak (VIORM), as defined by VDE 0884-17 for reinforced insulation. This corresponds to ~600 V_rms (VIOWM) and is distinct from the 1-minute dielectric test voltage of 5000 V_rms. The value is specified in Table 12 and Table 15, and applies to bipolar AC waveforms under pollution degree 2 and altitude ≤2000 m per IEC 60664-1.
