Product details

Overview

ADUM160N0BRZ-RL7 from Analog Devices is a 6-channel, 3.0 kV_RMS digital isolator based on iCoupler® transformer technology, designed for high-speed signal isolation across galvanic barriers in industrial and medical systems. It delivers 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and supports 1.8 V to 5 V level translation between isolated domains.

For engineers reviewing the ADUM160N0BRZ-RL7 datasheet, ADUM160N0BRZ-RL7 pinout, ADUM160N0BRZ-RL7 application, or ADUM160N0BRZ-RL7 equivalent, key selection criteria include reinforced insulation rating (VIORM = 565 V_peak), fail-safe high output configuration, common-mode transient immunity of 100 kV/µs, and operation up to +125°C ambient temperature.

Technical Context

The ADUM160N0BRZ-RL7 implements six independent unidirectional CMOS-isolated channels using monolithic air-core transformers, enabling dc-correct output behavior without input transitions. Its architecture ensures tight channel-to-channel propagation delay matching (≤4.0 ns) and low jitter (70 ps rms at 5 V).

It features dual-supply operation (VDD1/VDD2 = 1.7–5.5 V), undervoltage lockout (UVLO) with 1.6 V threshold, and failsafe logic-high output state when input-side power is absent-distinguishing it from ADUM160N1 variants with fail-safe low outputs.

Key Specifications

Parameter	Value and Actual Design Meaning
Data Rate	150 Mbps maximum guaranteed - supports high-speed SPI, RS-485, and digital I/O isolation without timing margin loss
Propagation Delay	13 ns max at 5 V - enables sub-10 ns timing budgets in real-time control loops
Common-Mode Transient Immunity	100 kV/µs - maintains signal integrity in noisy motor drives and switch-mode power supplies
Isolation Voltage	3000 V_RMS for 1 minute - meets reinforced insulation requirements per IEC/EN 62368-1 and IEC 60601-1
Fail-Safe Output State	High - ensures defined logic level during input-side power loss in safety-critical monitoring circuits
Operating Temperature	−40°C to +125°C - qualified for under-hood automotive, industrial PLC, and medical equipment environments
Supply Voltage Range	1.7 V to 5.5 V per side - enables mixed-voltage system interfacing (e.g., 1.8 V MCU to 3.3 V sensor)

Pinout & Package

ADUM160N0BRZ-RL7 uses a 16-lead, RoHS-compliant, narrow-body SOIC package (SOIC_N, body width 3.9 mm). Pin assignments are validated per Figure 17 (Pin Configurations) in Rev. B datasheet.

Pin/Terminal	Circuit Role	Design Meaning
VDD1	Primary-side supply	Power for input-side logic and channel drivers; accepts 1.7–5.5 V
GND1	Primary-side ground	Reference for all input signals and VDD1; must be separated from GND2 by ≥4.5 mm PCB clearance
INA, INB, INC, IND, INE, INF	Input data channels	CMOS-compatible inputs referenced to VDD1/GND1; support 1.8–5 V logic levels
VDD2	Secondary-side supply	Power for output-side logic; independent of VDD1, enabling level translation
GND2	Secondary-side ground	Reference for all outputs; galvanically isolated from GND1; requires ≥4.5 mm creepage
OUTA, OUTB, OUTC, OUTD, OUTE, OUTF	Output data channels	CMOS outputs referenced to VDD2/GND2; fail-safe high when VDD1 = 0 V

Key Features

Feature	Design Value
Reinforced insulation certification	DIN EN IEC 60747-17 (VDE 0884-17) and UL 1577 - eliminates need for external safety capacitors in Class I medical designs
DC-correct output behavior	No refresh pulses required - preserves static logic states indefinitely, unlike optocouplers
Tight propagation delay matching	≤4.0 ns channel-to-channel skew - critical for parallel bus isolation (e.g., ADC data lines)
Low dynamic power consumption	0.01 mA/Mbps input + 0.02 mA/Mbps output - reduces thermal load in dense isolation layouts
Robust UVLO protection	1.6 V turn-on / 1.5 V turn-off with 0.1 V hysteresis - prevents metastability during brown-out conditions

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM160N1BRZ-RL7	Identical specs except fail-safe output state is logic-low instead of logic-high	Required where default-off behavior is needed for safety shutdown (e.g., valve control)	Select ADUM160N1BRZ-RL7 only if system-level safety analysis mandates active-low default outputs
SI8660BB-B-IS	6-channel, 5 kV_RMS, but uses capacitive isolation; higher CMTI (150 kV/µs); no VDE 0884-17 certification	Suitable for non-medical industrial use where higher surge rating is prioritized over regulatory alignment	Choose SI8660BB-B-IS only when VDE 0884-17 compliance is not required and CMTI >100 kV/µs is critical

Compared with ADUM160N1BRZ-RL7, the ADUM160N0BRZ-RL7 provides fail-safe high outputs essential for enabling circuits; compared with SI8660BB-B-IS, it offers certified reinforced insulation for medical and safety-critical systems but trades 2 kV_RMS isolation margin for regulatory assurance.

FAQ

What is the fail-safe output behavior of ADUM160N0BRZ-RL7?

The ADUM160N0BRZ-RL7 features a fail-safe high output configuration: when VDD1 is unpowered or below UVLO threshold (1.5 V), all six outputs transition to and hold logic-high state. This behavior is confirmed in the Truth Table (page 16) and Functional Block Diagram (Figure 1) of the Rev. B datasheet, distinguishing it from the N1 variant which defaults low.

Does ADUM160N0BRZ-RL7 support 1.8 V operation on both sides?

Yes, ADUM160N0BRZ-RL7 operates with VDD1 and VDD2 independently configurable from 1.7 V to 5.5 V. Electrical Characteristics tables for 1.8 V operation (Table 7) confirm 15 ns max propagation delay, 150 Mbps data rate, and full functionality - enabling direct interface with ultra-low-voltage MCUs and sensors.

What safety certifications apply to ADUM160N0BRZ-RL7?

ADUM160N0BRZ-RL7 holds UL 1577 (3000 V_RMS), DIN EN IEC 60747-17 (VDE 0884-17), IEC/CSA 62368-1, IEC/CSA 60601-1 (2×MOPP), and IEC/CSA 61010-1 approvals. Certification details appear in Table 11 and Regulatory Information section (page 12) of the datasheet.

How does ADUM160N0BRZ-RL7 achieve dc correctness without refresh cycles?

ADUM160N0BRZ-RL7 uses iCoupler® monolithic air-core transformers with integrated refresh circuitry that detects static input states and sustains output levels indefinitely - unlike optocouplers requiring periodic input toggling. This is explicitly stated in the General Description (page 1) and ensures reliable latching of control signals during idle periods.

What is the minimum PCB creepage and clearance required for ADUM160N0BRZ-RL7?

Per Table 9 (page 12), ADUM160N0BRZ-RL7 requires minimum external creepage of 4.0 mm and minimum PCB clearance of 4.5 mm between input-side (Pins 1–8) and output-side (Pins 9–16) terminals. These values satisfy IEC 62368-1 pollution degree 2 requirements at ≤2000 m altitude.
