Product details

Overview

ADUM110N1BRZ-RL7 from Analog Devices is a single-channel, 3.0 kV_RMS digital isolator based on iCoupler® transformer technology, providing galvanic isolation between logic domains. It delivers 150 Mbps data rate, 13 ns max propagation delay at 5 V, and operates across 1.8 V to 5 V supply ranges on both sides-enabling level translation in industrial field bus interfaces and isolated sensor signal conditioning.

For engineers reviewing the ADUM110N1BRZ-RL7 datasheet, ADUM110N1BRZ-RL7 pinout, ADUM110N1BRZ-RL7 application, or ADUM110N1BRZ-RL7 equivalent, key selection criteria include its reinforced insulation rating (VIORM = 565 V_PEAK), fail-safe high output state (N1 variant), 100 kV/µs common-mode transient immunity, and SOIC-8 RoHS-compliant package compatibility with legacy ADuM1100 designs.

Technical Context

The ADUM110N1BRZ-RL7 implements on-off keying (OOK) modulation across monolithic air-core transformers, ensuring DC-correct output without input transitions. Its dual-supply architecture supports independent 1.7 V–5.5 V operation on each side, enabling bidirectional voltage translation (e.g., 1.8 V logic to 3.3 V system).

Fail-safe behavior is hardwired: when VDD1 is unpowered, the N1 variant forces VO high; undervoltage lockout activates at 1.5 V (hysteresis 0.1 V). Internal regulators and differential OOK detection deliver robust noise immunity-validated by 100 kV/µs CMTI and <3 ns pulse width distortion at 5 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Data Rate	150 Mbps maximum - supports high-speed serial links like isolated UART, SPI clock lines, or digital I/O in PLC backplanes.
Propagation Delay	13 ns max at 5 V - enables tight timing budgets in real-time control loops and fast feedback paths.
Common-Mode Transient Immunity	100 kV/µs - maintains signal integrity during fast-switching events in motor drives or power converters.
Isolation Rating	3000 V_RMS for 1 minute - certified for reinforced insulation per UL 1577, IEC 60601-1, and VDE 0884-17.
Supply Range	1.7 V to 5.5 V on both sides - allows interoperability between 1.8 V microcontrollers and 5 V legacy peripherals.
Fail-Safe Output	High (N1) - ensures defined logic-high state during input-side power loss, critical for safety interlocks.
Package	8-lead SOIC (SOIC_W), 5.3 mm body width - standard footprint compatible with automated SMT assembly and ADuM1100 layouts.

Pinout & Package

ADUM110N1BRZ-RL7 uses an 8-lead, RoHS-compliant SOIC_W package with creepage/clearance ≥4.0 mm and internal polyimide insulation. Pin 1–4 form the input side (VDD1, VI, VDD1, GND1); pins 5–8 form the output side (GND2, VO, GND2, VDD2).

Pin/Terminal	Circuit Role	Design Meaning
1, 3	VDD1	Input-side supply - must be bypassed with 0.01–0.1 µF capacitor to GND1; powers input logic and transmitter.
2	VI	Unidirectional logic input - accepts CMOS levels; no external pull-up/down required.
4	GND1	Input-side ground reference - forms isolation barrier boundary with GND2; must be physically separated on PCB.
5, 7	GND2	Output-side ground - reference for VO and receiver; routed separately from GND1 to maintain isolation integrity.
6	VO	Logic output - provides rail-to-rail CMOS-compatible signal; fails high when VDD1 is absent (N1 behavior).
8	VDD2	Output-side supply - powers receiver and output driver; independent of VDD1, enabling level translation.

Key Features

Feature	Design Value
Reinforced insulation certification	DIN EN IEC 60747-17 (VDE 0884-17) approved - enables use in medical (1 MOPP) and industrial safety-critical systems without additional barrier components.
DC-correct transmission	Maintains output state during static input - eliminates need for refresh clocks or watchdog timers in low-duty-cycle monitoring applications.
Low dynamic power	0.01–0.02 mA/Mbps - reduces thermal load in dense isolation arrays and extends battery life in portable isolated sensors.
High temperature operation	Rated from −40°C to +125°C - supports under-hood automotive, motor drive, and industrial ambient environments without derating.
Backward pin compatibility	Direct replacement for ADuM1100 - allows drop-in upgrade to higher speed (150 vs. 100 Mbps) and improved CMTI without PCB redesign.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM1100ARZ-RL7	Lower 100 Mbps data rate; 25 ns max propagation delay; same SOIC-8 package and pinout.	Lacks fail-safe high option (only default-low N0 variant); lower CMTI (50 kV/µs).	Select when cost sensitivity outweighs speed/CMTI needs and fail-safe high is unnecessary.
SI8610BD-B-IS	Capacitive isolation; 150 Mbps; 12 ns max propagation delay; 5 kV_RMS rating; SOIC-8 package.	No native fail-safe option; requires external circuitry for defined output during power loss.	Choose for higher isolation voltage margin and lower jitter, but verify fail-safe behavior via external design.

Compared with ADUM110N1BRZ-RL7, ADUM1100ARZ-RL7 offers lower performance at reduced cost, while SI8610BD-B-IS trades fail-safe integration for higher isolation voltage and slightly better timing-neither is pin-compatible without layout review due to differing internal architecture and biasing requirements.

FAQ

What is the fail-safe behavior of ADUM110N1BRZ-RL7?

The ADUM110N1BRZ-RL7 is the N1 variant, meaning its output defaults to logic high when the input-side supply (VDD1) is unpowered or disabled. This behavior is intrinsic to the device's internal architecture and requires no external components. During normal operation with both VDD1 and VDD2 powered, ADUM110N1BRZ-RL7 transmits input logic states faithfully with <3 ns pulse width distortion.

Does ADUM110N1BRZ-RL7 support level translation between different logic voltages?

Yes, ADUM110N1BRZ-RL7 supports bidirectional level translation between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains. Its input threshold scales with VDD1 (VIH = 0.7 × VDD1), and output swing tracks VDD2 (VOH ≈ VDD2 − 0.2 V), enabling direct interface between disparate voltage rails without external level shifters.

What safety certifications apply to ADUM110N1BRZ-RL7?

ADUM110N1BRZ-RL7 is certified to UL 1577 (3000 V_RMS), IEC/EN/CSA 60950-1, IEC/CSA 60601-1 (1 MOPP), IEC/CSA 61010-1, and DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation. Its VIORM = 565 V_PEAK and minimum creepage/clearance of 4.0 mm meet stringent medical and industrial safety standards.

Can ADUM110N1BRZ-RL7 replace ADUM1100ARZ-RL7 without PCB changes?

Yes, ADUM110N1BRZ-RL7 is pin-compatible with ADUM1100ARZ-RL7 and uses the same SOIC-8 footprint, pad layout, and bypassing requirements. However, designers must verify that the N1 fail-safe high behavior aligns with system safety logic, as ADUM1100ARZ-RL7 only offers N0 (fail-low) variants.

What is the maximum operating temperature for ADUM110N1BRZ-RL7?

ADUM110N1BRZ-RL7 is rated for continuous operation from −40°C to +125°C ambient temperature. Its thermal resistance (θ_JA) is 80°C/W, and internal safety limiting values-including junction temperature (150°C) and total power dissipation (1.56 W at 25°C)-are specified per DIN EN IEC 60747-17.
