Analog Devices Inc. ADUM162N1BRZ-RL7

Overview

ADUM162N1BRZ-RL7 from Analog Devices is a 6-channel, 3.0 kV_RMS digital isolator based on iCoupler® monolithic air-core transformer technology. It delivers 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and 100 kV/µs common-mode transient immunity. It supports 1.8 V to 5.5 V dual-supply operation with level translation and fail-safe high output configuration, used in SPI isolation for industrial PLC I/O modules.

For engineers reviewing the ADUM162N1BRZ-RL7 datasheet, ADUM162N1BRZ-RL7 pinout, ADUM162N1BRZ-RL7 application, or ADUM162N1BRZ-RL7 equivalent, key selection criteria include reinforced insulation rating (VIORM = 565 V_peak), channel-to-channel skew ≤4.0 ns, thermal derating compliance per DIN EN IEC 60747-17, and SOIC_N-16 package compatibility with IPC-7351B footprint standards.

Technical Context

The ADUM162N1BRZ-RL7 implements six independent unidirectional CMOS-isolated channels using bidirectional air-core transformers and integrated DC-correcting logic. Its architecture ensures dc correctness without input transitions and supports fail-safe high output state when VDD1 is unpowered.

It operates across dual isolated supplies (VDD1/VDD2) from 1.7 V to 5.5 V, enabling voltage translation between domains. Propagation delay matching is specified at ≤4.0 ns codirectional skew and ≤4.5 ns opposing-direction skew over −40°C to +125°C.

FAQ

What is the maximum guaranteed data rate for ADUM162N1BRZ-RL7?

The ADUM162N1BRZ-RL7 guarantees a maximum data rate of 150 Mbps across all six channels under specified operating conditions (CL = 15 pF, CMOS levels). This value is validated per the datasheet's Electrical Characteristics tables and applies over the full temperature and voltage range. Higher rates may be achievable but are not production-tested or guaranteed. The ADUM162N1BRZ-RL7 achieves this performance while maintaining pulse width distortion below 5 ns and jitter under 500 ps p-p.

Does ADUM162N1BRZ-RL7 support 1.8 V operation on both sides?

Yes, ADUM162N1BRZ-RL7 supports 1.8 V operation on both VDD1 and VDD2 sides, with minimum supply voltage of 1.7 V and maximum of 5.5 V per side. At 1.8 V, propagation delay is specified at 15 ns maximum and data rate remains 150 Mbps. Input thresholds scale with supply (VIH = 0.7 × VDDx), and output drive capability is maintained at 2 mA sink/source, making ADUM162N1BRZ-RL7 suitable for ultra-low-power microcontroller interfaces.

What safety certifications does ADUM162N1BRZ-RL7 hold?

ADUM162N1BRZ-RL7 holds UL 1577 (3000 V_RMS, 1 min), DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation (VIORM = 565 V_peak), IEC/CSA 62368-1, IEC/CSA 60601-1 (1 MOPP), and CQC GB 4943.1. These certifications are verified via 100% production partial discharge testing at 1059 V_peak. The device is branded with * marking indicating VDE 0884-17 compliance, critical for medical and industrial safety approvals.

How does the fail-safe high feature work on ADUM162N1BRZ-RL7?

The ADUM162N1BRZ-RL7 implements fail-safe high output: when VDD1 is unpowered or drops below UVLO threshold (1.5 V), all six outputs transition to and remain at logic high. This behavior is implemented via internal bias circuitry independent of input signals. It prevents floating or undefined states in safety-critical interfaces such as gate driver enables or emergency stop monitoring. The feature is inherent to the N1 variant and does not require external components.

What is the channel-to-channel propagation delay skew for ADUM162N1BRZ-RL7?

ADUM162N1BRZ-RL7 specifies maximum channel-to-channel propagation delay skew of 4.0 ns for codirectional signals (e.g., all inputs driven simultaneously) and 4.5 ns for opposing-direction signals (e.g., input→output vs. output→input paths), measured across temperature (−40°C to +125°C) and supply (1.7–5.5 V). This tight skew enables precise timing alignment in multi-channel SPI daisy chains and synchronized ADC sampling, directly supporting time-critical industrial control applications.
