Product details
Overview
ADUM3100BRZ-RL7 from Analog Devices is a single-channel digital isolator based on iCoupler® transformer technology, providing reinforced galvanic isolation between input and output domains. It supports up to 100 Mbps data rate at 5 V operation, features <18 ns propagation delay, 25 kV/μs common-mode transient immunity, and operates across −40°C to +105°C for industrial fieldbus interface applications.
For engineers reviewing the ADUM3100BRZ-RL7 datasheet, ADUM3100BRZ-RL7 pinout, ADUM3100BRZ-RL7 application, or ADUM3100BRZ-RL7 equivalent, key selection criteria include maximum data rate (100 Mbps), dual-supply level translation (3.3 V/5 V), system-level ESD robustness per IEC 61000-4-x, and UL/VDE-reinforced insulation certification (VIORM = 560 V peak).
Technical Context
The ADUM3100BRZ-RL7 implements monolithic air-core transformers for signal transmission across an isolation barrier, eliminating LED aging and timing drift inherent in optocouplers. Its patented refresh circuit ensures DC correctness without periodic re-synchronization.
It supports asymmetric supply configurations (e.g., 5 V input / 3.3 V output), delivers <2 ns edge asymmetry, and maintains pulse-width distortion ≤2 ns over temperature - critical for high-speed serial interfaces like RS-485 transceivers and isolated SPI clock lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 100 Mbps - supports full-duplex UART, isolated CAN FD physical layer signaling, and high-speed sensor interface protocols |
| Propagation Delay | <18 ns - enables tight timing budgets in real-time control loops and fast feedback systems |
| Common-Mode Transient Immunity | >25 kV/μs - sustains reliable operation in motor drive inverters and industrial PLC backplanes with rapid voltage transients |
| Isolation Rating | 2500 V rms (1 min), VIORM = 560 V peak - certified for reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17) |
| Supply Voltage Range | 3.0 V to 5.5 V per side - allows direct interfacing with 3.3 V microcontrollers and 5 V legacy peripherals without level shifters |
| Quiescent Current (5 V) | ≤2.0 mA total - reduces standby power in battery-backed or energy-sensitive isolated gate drivers |
| Operating Temperature | −40°C to +105°C - qualified for under-hood automotive subsystems and industrial motor control enclosures |
Pinout & Package
ADUM3100BRZ-RL7 is housed in an RoHS-compliant, wide-body 8-lead SOIC package (SOIC_W) with creepage/clearance ≥4 mm and internal insulation gap ≥18 μm, rated for reinforced isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | VDD1 | Input-side power supply (3.0–5.5 V); pins must be decoupled locally to minimize noise coupling across isolation barrier |
| 2 | VI | Unidirectional logic input; accepts CMOS-compatible thresholds (VIH ≥2.0 V @ 5 V, ≥1.5 V @ 3.3 V) |
| 4 | GND1 | Input-side reference ground; must be separated from GND2 by ≥4 mm PCB clearance to maintain isolation integrity |
| 5, 7 | GND2 | Output-side reference ground; forms return path for VO and VDD2; shares no conductive connection with GND1 |
| 6 | VO | Isolated logic output; drives CMOS loads up to 4 mA while maintaining VOL ≤0.1 V and VOH ≥VDD2 − 0.1 V |
| 8 | VDD2 | Output-side power supply (3.0–5.5 V); enables level translation independent of VDD1 |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced System-Level ESD Reliability | Validated per IEC 61000-4-2/4-4/4-5 - reduces board-level failure risk in factory automation and medical equipment without external TVS |
| DC-Correct Output with Refresh | Patented refresh circuit maintains output state during extended DC input periods - eliminates data loss in slow-control signals (e.g., enable lines) |
| Low-Power Dynamic Scaling | Dynamic current ≤0.09 mA/Mbps on input side - enables predictable power budgeting for variable-rate communication links |
| High CMTI with Fast Edges | 25 kV/μs immunity combined with 3 ns rise/fall time - prevents metastability in noisy switch-mode power supply monitoring circuits |
| UL + VDE Reinforced Certification | Single-component compliance to UL 1577 (2500 V rms), VDE 0884-17 (560 V peak), and IEC 62368-1 - simplifies safety certification for end equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM3100ARZ-RL7 | Lower max data rate (25 Mbps), higher minimum pulse width (40 ns), same package and pinout | Suitable for slower control signals (e.g., GPIO, enable lines) where 100 Mbps is unnecessary | Select ADUM3100ARZ-RL7 when system data rate ≤25 Mbps and lower dynamic power consumption is prioritized |
| SI8600BD-B-IS | Capacitive isolation, 100 Mbps rating, 2.5 kV rms isolation, different pinout (SOIC-8 but non-pin-compatible) | Lacks VDE-reinforced certification (only basic insulation), requires layout redesign for replacement | Choose SI8600BD-B-IS only if UL 1577 compliance suffices and board re-spin is acceptable |
Compared with ADUM3100ARZ-RL7, the ADUM3100BRZ-RL7 enables faster serial protocols without changing PCB layout; versus SI8600BD-B-IS, it provides certified reinforced insulation and guaranteed system-level ESD performance without requiring board-level redesign.

FAQ
What is the maximum data rate supported by the ADUM3100BRZ-RL7?
The ADUM3100BRZ-RL7 supports a maximum data rate of 100 Mbps under 5 V operation with CMOS signal levels and 15 pF load. At 3.3 V operation, its guaranteed maximum data rate is 50 Mbps. These values are specified with pulse-width distortion ≤2 ns and apply across the full −40°C to +105°C operating temperature range.
Does the ADUM3100BRZ-RL7 support level translation between different supply voltages?
Yes, the ADUM3100BRZ-RL7 supports mixed-supply operation: VDD1 can be 3.3 V while VDD2 is 5 V, or vice versa. Input logic thresholds scale with VDD1, and output drive strength adapts to VDD2, enabling seamless interfacing between 3.3 V microcontrollers and 5 V peripherals without external level shifters.
What safety certifications does the ADUM3100BRZ-RL7 hold?
The ADUM3100BRZ-RL7 is certified for reinforced isolation per DIN EN IEC 60747-17 (VDE 0884-17), UL 1577 (2500 V rms, 1 minute), IEC/EN/CSA 62368-1, and IEC/CSA 61010-1. Its VIORM rating is 560 V peak, and it carries the VDE reinforcement mark (*) on the package body.
How does the ADUM3100BRZ-RL7 ensure DC correctness?
The ADUM3100BRZ-RL7 uses a patented refresh circuit that continuously monitors and updates the output state during extended DC input conditions. This ensures the VO pin retains the correct logic level even when VI remains static for seconds or minutes - a capability absent in standard optocouplers and essential for control signal integrity.
What is the common-mode transient immunity (CMTI) specification for the ADUM3100BRZ-RL7?
The ADUM3100BRZ-RL7 guarantees >25 kV/μs common-mode transient immunity at both logic low and high output states, tested with 1000 V common-mode step and 800 V transient magnitude. This performance is maintained across temperature and supply voltage variations, making it suitable for noisy motor drive and power supply monitoring applications.
