Product details

Overview

ADUM151N0BRZ-RL7 from Analog Devices is a 5-channel, 3.0 kV_RMS reinforced digital isolator using iCoupler® transformer-based technology. It supports 150 Mbps data rate, 13 ns max propagation delay at 5 V, and 1.8 V to 5.5 V dual-supply operation with level translation. It is used in SPI isolation for industrial PLCs where high CMTI (>100 kV/µs) and fail-safe output behavior are required.

For engineers reviewing the ADUM151N0BRZ-RL7 datasheet, ADUM151N0BRZ-RL7 pinout, ADUM151N0BRZ-RL7 application, or ADUM151N0BRZ-RL7 equivalent, key selection criteria include reinforced insulation rating (VIORM = 565 V_peak), channel-to-channel skew ≤4.0 ns, SOIC_N-16 package compatibility, and fail-safe low output state on input-side power loss.

Technical Context

The ADUM151N0BRZ-RL7 implements five independent unidirectional CMOS-isolated channels using monolithic air-core transformers, enabling dc-correct signal transmission without refresh cycles. Its architecture ensures deterministic timing with tight channel matching (≤4.0 ns codirectional skew) and low jitter (70 ps rms at 5 V).

It features dual independent supply domains (VDD1/VDD2), allowing 1.8 V ↔ 5 V level translation across the isolation barrier. Fail-safe logic is implemented via internal detection of VDD1 undervoltage (UVLO threshold = 1.6 V), forcing outputs low when input power is absent.

Key Specifications

Parameter	Value and Actual Design Meaning
Data Rate	150 Mbps maximum - guarantees full-speed SPI, RS-485, and CAN FD interface isolation without oversampling or retiming.
Propagation Delay	13 ns max at 5 V - enables sub-20 ns round-trip latency in closed-loop motor control feedback paths.
CMTI	100 kV/µs minimum - sustains reliable operation in high-noise variable-frequency drive (VFD) gate driver environments.
Isolation Rating	3000 V_RMS for 1 minute - meets reinforced insulation requirements per IEC 62368-1, IEC 60601-1, and DIN EN IEC 60747-17 (VDE 0884-17).
Supply Range	1.7 V to 5.5 V per side - supports direct interfacing with 1.8 V microcontrollers and 3.3/5 V peripherals without external level shifters.
Fail-Safe Output	Low-state default on VDD1 loss - prevents undefined states in safety-critical I/O modules during controller power interruption.
VIORM	565 V_peak - defines maximum continuous working voltage under reinforced insulation, critical for medical and industrial mains-connected systems.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SI8650BB-B-IS	5-channel, 5 kV_RMS, capacitive isolation; 150 Mbps; 13 ns delay; 2.5–5.5 V supply; failsafe configurable via pin.	Higher isolation rating but lacks 1.8 V operation; requires external pull-up for fail-safe high mode.	Preferred where higher creepage/clearance or UL 62368-1 certification is mandatory; not suitable for 1.8 V microcontroller interfaces.
ISO6751-Q1	5-channel, 5000 V_RMS, capacitive isolation; 50 Mbps; 25 ns delay; 1.7–5.5 V; failsafe low default.	Lower data rate and higher propagation delay; AEC-Q100 qualified for automotive use.	Appropriate for automotive body control modules requiring ISO 26262 ASIL-B compliance; insufficient for high-speed SPI or encoder feedback.

Compared with SI8650BB-B-IS and ISO6751-Q1, ADUM151N0BRZ-RL7 uniquely combines 1.8 V operation, 150 Mbps speed, and factory-configured fail-safe low output in a single SOIC_N-16 package-making it optimal for space-constrained industrial controllers needing wide supply flexibility and deterministic safety behavior.

FAQ

What is the fail-safe output behavior of ADUM151N0BRZ-RL7?

The ADUM151N0BRZ-RL7 is configured as an N0 variant, meaning its outputs default to logic low when VDD1 is unpowered or drops below UVLO threshold (1.6 V). This behavior is hardwired and does not require external components. The ADUM151N0BRZ-RL7 maintains this fail-safe state across its full −40°C to +125°C operating range, ensuring predictable shutdown in power-loss scenarios.

Does ADUM151N0BRZ-RL7 support 1.8 V operation on both sides?

Yes, ADUM151N0BRZ-RL7 supports 1.7 V to 5.5 V independently on VDD1 and VDD2. At 1.8 V operation, it delivers 15 ns max propagation delay and 150 Mbps data rate with full specification compliance. This allows direct interfacing with 1.8 V FPGAs or microcontrollers on one side and 3.3 V or 5 V peripherals on the other-no level shifters needed.

What safety certifications apply to ADUM151N0BRZ-RL7?

ADUM151N0BRZ-RL7 carries UL 1577 (3000 V_RMS), DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation (VIORM = 565 V_peak), IEC/CSA 62368-1, IEC/CSA 60601-1 (1 MOPP), and IEC/CSA 61010-1 approvals. Certificate numbers include CQC GB 4943.1 (CQC18001196412) and VDE 40051926.

How does ADUM151N0BRZ-RL7 compare to optocouplers in terms of timing performance?

ADUM151N0BRZ-RL7 achieves 13 ns max propagation delay and ≤4.0 ns channel-to-channel skew-over 10× tighter than typical high-speed optocouplers (e.g., 6N137: 75 ns delay, >20 ns skew). Its jitter is 70 ps rms vs. >1 ns for optocouplers, enabling precise timing in servo control loops and high-speed data capture where deterministic latency is critical.

Can ADUM151N0BRZ-RL7 be used in medical applications requiring 2 MOPP?

No. ADUM151N0BRZ-RL7 is certified for 1 MOPP per IEC 60601-1 (250 V_RMS basic insulation), sufficient for patient-connected devices with single-fault protection. For 2 MOPP systems (e.g., defibrillator-rated equipment), two ADUM151N0BRZ-RL7 devices in series or a dedicated 2-MOPP isolator like ADUM141D0BRWZ would be required.
