Analog Devices Inc. ADUM163N1BRZ-RL7

Overview

ADUM163N1BRZ-RL7 from Analog Devices is a 6-channel, 3.0 kV_RMS reinforced digital isolator based on iCoupler® technology, designed for high-noise industrial and medical systems requiring galvanic separation between microcontroller peripherals and isolated bus interfaces. It delivers 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, 100 kV/µs common-mode transient immunity, and operates across 1.7 V to 5.5 V supply rails on both sides - enabling level translation in SPI, RS-485, and I²C isolation applications.

For engineers reviewing the ADUM163N1BRZ-RL7 datasheet, ADUM163N1BRZ-RL7 pinout, ADUM163N1BRZ-RL7 application, or ADUM163N1BRZ-RL7 equivalent, this page provides verified specifications, fail-safe output behavior, safety certification details (UL 1577, VDE 0884-17), package dimensions, and real-world use cases for multichannel signal isolation in harsh EMI environments.

Technical Context

The ADUM163N1BRZ-RL7 implements six independent unidirectional CMOS-isolated channels using monolithic air-core transformers, with no optocoupler aging or LED degradation. Its architecture ensures DC correctness without input transitions and supports two fail-safe states (high or low) upon loss of input-side power.

It features tight channel-to-channel propagation delay matching (≤4.0 ns), low jitter (70 ps rms), and robust insulation with VIORM = 565 V_peak, rated for reinforced isolation per DIN EN IEC 60747-17 and IEC/CSA 60601-1 - making it suitable for patient-connected medical equipment and industrial PLC backplanes.

Key Specifications

Pinout & Package

ADUM163N1BRZ-RL7 uses a 16-lead, RoHS-compliant narrow-body SOIC package (SOIC_N) with 7.5 mm body width and 1.27 mm pitch. Input-side pins (1–8) and output-side pins (9–16) are physically separated to maximize creepage and clearance (≥4.0 mm).

FAQ

What safety certifications does the ADUM163N1BRZ-RL7 hold?

The ADUM163N1BRZ-RL7 is certified to UL 1577 (3000 V_RMS), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation, IEC/CSA 62368-1, IEC/CSA 60601-1 (2× MOPP), and IEC/CSA 61010-1. These approvals validate its use in medical devices, industrial controls, and test equipment where patient or operator safety depends on reliable isolation.

Does the ADUM163N1BRZ-RL7 support 1.8 V logic levels on both sides?

Yes, the ADUM163N1BRZ-RL7 operates with supply voltages from 1.7 V to 5.5 V on both VDD1 and VDD2, enabling true 1.8 V ↔ 1.8 V, 1.8 V ↔ 3.3 V, or 1.8 V ↔ 5 V level translation. At 1.8 V operation, it guarantees 150 Mbps data rate and 15 ns maximum propagation delay - confirmed in Table 7 of the Rev. B datasheet.

How does the fail-safe output configuration work on the ADUM163N1BRZ-RL7?

The ADUM163N1BRZ-RL7 is the N1 variant, meaning its outputs default to logic high when VDD1 is unpowered or below UVLO threshold (1.5 V). This behavior prevents undefined states in safety-critical monitoring circuits - for example, keeping an enable line asserted during MCU reset or brownout conditions.

What is the minimum creepage and clearance distance achieved by the ADUM163N1BRZ-RL7 package?

The ADUM163N1BRZ-RL7 in its narrow-body SOIC package achieves ≥4.0 mm minimum external creepage and ≥4.01 mm minimum external clearance between input and output pins. PCB layout must maintain ≥4.5 mm line-of-sight clearance in the mounting plane to meet IEC 62368-1 pollution degree 2 requirements.

Can the ADUM163N1BRZ-RL7 replace older ADuM160N or ADuM161N series parts?

Yes, the ADUM163N1BRZ-RL7 is pin-compatible with other ADuM16xN variants in the same SOIC_N-16 package and shares identical pinout, timing, and electrical characteristics. Its N1 fail-safe configuration and optimized quiescent current (e.g., 3.0 mA IDD1(Q) at VDD1=5 V, VI5=0) make it a direct drop-in upgrade for designs requiring enhanced reliability and lower static power.
