Product details
Overview
ADUM110N0BRZ-RL7 from Analog Devices is a single-channel, 3.0 kVRMS reinforced digital isolator using iCoupler® transformer-based technology. It delivers 150 Mbps data rate, 13 ns max propagation delay at 5 V, and 100 kV/µs common-mode transient immunity. Designed for fail-safe low output (N0 variant), it supports 1.8 V to 5 V bidirectional level translation across the isolation barrier and operates from −40°C to +125°C - ideal for industrial field bus interfaces requiring robust noise immunity and safety-certified isolation.
For engineers reviewing the ADUM110N0BRZ-RL7 datasheet, ADUM110N0BRZ-RL7 pinout, ADUM110N0BRZ-RL7 application, or ADUM110N0BRZ-RL7 equivalent, this page provides verified technical context, exact pin functions, real-world use cases in isolated communication links, and validated alternative options with documented functional and safety differences.
Technical Context
The ADUM110N0BRZ-RL7 implements on-off keying (OOK) modulation over monolithic air-core transformers, enabling dc-correct signal transmission without input transitions. Its differential architecture ensures high-speed operation while maintaining <3 ns pulse width distortion and <15 ns max propagation delay across 1.8–5 V supply ranges.
It integrates independent undervoltage lockout (UVLO) on both sides (VDDxUV+ = 1.6 V), dual ground-referenced domains (GND1/GND2), and fail-safe logic that forces VO = low when VDD1 is unpowered - a behavior confirmed exclusively for the N0 variant per Truth Table and Ordering Guide.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3000 VRMS for 1 minute - certified reinforced insulation per UL 1577, VDE 0884-17, and IEC 60601-1. |
| Data Rate | 150 Mbps maximum - supports high-speed serial protocols including SPI, RS-485, and CAN FD physical layer isolation. |
| Propagation Delay | 13 ns max at 5 V - enables tight timing budgets in real-time control loops and fast feedback systems. |
| Common-Mode Immunity | 100 kV/µs - sustains reliable operation in noisy motor drives and industrial PLC backplanes. |
| Supply Range | 1.7 V to 5.5 V per side - allows direct interfacing between 1.8 V microcontrollers and 5 V field-side peripherals. |
| Fail-Safe Output | Low-state default (N0) - VO driven low when VDD1 is absent, preventing undefined states in power-loss scenarios. |
| Package | 8-lead SOIC (SOIC_W), 5.3 mm creepage/clearance - meets IEC 60950-1 pollution degree 2 requirements. |
Pinout & Package
ADUM110N0BRZ-RL7 uses an 8-lead, RoHS-compliant SOIC_W package with gull-wing leads. Input and output sides are fully galvanically isolated: Pins 1–4 form Side 1 (input domain); Pins 5–8 form Side 2 (output domain). Minimum PCB creepage is 4.5 mm in-plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | VDD1 | Input-side supply voltage (1.7–5.5 V); must be bypassed locally with 0.01–0.1 µF capacitor to Pin 4. |
| 2 | VI | Single-ended CMOS-compatible logic input; accepts 1.7–5.5 V logic levels regardless of VDD1. |
| 4 | GND1 | Input-side ground reference; forms isolation barrier boundary with GND2 (Pins 5 & 7). |
| 5, 7 | GND2 | Output-side ground reference; electrically isolated from GND1 by polyimide insulation. |
| 6 | VO | CMOS output referenced to VDD2; fails low when VDD1 is unpowered (N0 behavior). |
| 8 | VDD2 | Output-side supply voltage (1.7–5.5 V); bypass capacitor required between Pin 8 and Pin 5 or 7. |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Eliminates LED aging and CTR degradation of optocouplers; guarantees >50-year insulation lifetime per VDE 0884-17. |
| Reinforced insulation | VIORM = 565 VPEAK, VIOWM = 400 VRMS - enables single-component isolation in medical (1 MOPP) and industrial safety-critical systems. |
| Level translation | 1.8 V ↔ 5 V bidirectional compatibility - permits mixed-voltage system design without external level shifters. |
| Fail-safe N0 output | Guaranteed low output during VDD1 loss - prevents spurious actuation in motor control or valve driver circuits. |
| Low dynamic power | 0.01 mA/Mbps dynamic current - reduces heat generation in dense isolation arrays and battery-powered gate drivers. |
Applications
| Industrial Field Bus Isolation | Medical Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM110N1BRZ-RL7 | Identical specs except fail-safe output is high (N1), not low (N0); same pinout and isolation ratings. | Required where system safety logic mandates active-high fault signaling or default-on behavior after power loss. | Select only if fail-safe state must be high; N0/N1 are not interchangeable without firmware or logic redesign. |
| SI8610BB-B-IS | Capacitive isolation; 5 kVRMS rating; 150 Mbps; but VIORM = 400 VPEAK (basic, not reinforced) and no IEC 60601-1 approval. | Suitable for industrial controls without medical/safety certification, but cannot replace ADUM110N0BRZ-RL7 in 1 MOPP designs. | Use only in non-safety-critical applications; requires layout review for CMTI (75 kV/µs typical) and creepage compliance. |
Compared with ADUM110N0BRZ-RL7, the ADUM110N1BRZ-RL7 offers identical performance with inverted fail-safe behavior, while the SI8610BB-B-IS trades regulatory coverage (no 60601-1) and lower VIORM for higher isolation voltage rating - making it unsuitable for medical or reinforced-insulation systems.

FAQ
What is the fail-safe behavior of ADUM110N0BRZ-RL7?
The ADUM110N0BRZ-RL7 features a fail-safe low output: when VDD1 is unpowered or disabled, the VO pin is actively driven low. This behavior is hard-coded into the N0 variant and confirmed in the Truth Table (Table 16) and General Description. It prevents undefined logic states during input-side power loss - critical for safety interlocks and motor control shutdown sequences. The ADUM110N0BRZ-RL7 does not float or enter high-impedance mode under these conditions.
Does ADUM110N0BRZ-RL7 support 1.8 V operation on both sides simultaneously?
Yes, ADUM110N0BRZ-RL7 supports 1.8 V operation on both VDD1 and VDD2 simultaneously. Electrical Characteristics tables confirm full functionality at 1.8 V, including 15 ns max propagation delay, 150 Mbps data rate, and 100 kV/µs CMTI. The device maintains dc correctness and fail-safe behavior across the entire 1.7–5.5 V range per side, enabling true 1.8 V ↔ 1.8 V isolation without level translation overhead.
What safety certifications apply to ADUM110N0BRZ-RL7?
ADUM110N0BRZ-RL7 carries UL 1577 (3000 VRMS), VDE 0884-17 (DIN EN IEC 60747-17), IEC/EN/CSA 60950-1, IEC/CSA 60601-1 (1 MOPP), and IEC/CSA 61010-1 approvals. These are explicitly listed in Table 11 and Regulatory Information. The * marking on the package denotes VDE 0884-17 compliance. No additional third-party validation is needed - all certifications apply directly to the ADUM110N0BRZ-RL7 part number.
Is ADUM110N0BRZ-RL7 pin-compatible with ADUM1100?
Yes, ADUM110N0BRZ-RL7 is pin-compatible with the ADUM1100 family per the Features section and General Description. Both share identical 8-lead SOIC pin configuration (VDD1, VI, VDD1, GND1, GND2, VO, GND2, VDD2), same footprint, and compatible voltage and timing specifications. However, ADUM110N0BRZ-RL7 improves propagation delay (13 ns vs. 25 ns) and CMTI (100 kV/µs vs. 25 kV/µs), so it can be used as a drop-in upgrade where enhanced speed and noise immunity are required.
What is the maximum continuous working voltage for ADUM110N0BRZ-RL7 in reinforced insulation mode?
For reinforced insulation, ADUM110N0BRZ-RL7 has a maximum continuous working voltage (VIOWM) of 400 VRMS for AC bipolar waveforms and 469 VPEAK for unipolar waveforms, as specified in Table 15. These values are derived from package creepage (4.0 mm) and material group II (CTI > 400 V) per IEC 60664-1. Exceeding these voltages voids safety certification and risks insulation breakdown over time.
