Analog Devices Inc. ADUM260N1BRIZ

Overview

ADuM260N1BRIZ from Analog Devices is a 6-channel, 5.0 kV_RMS reinforced digital isolator using iCoupler® 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 V level translation and operates from −40°C to +125°C - used in SPI isolation for industrial PLCs with high-noise motor drive interfaces.

For engineers reviewing the ADuM260N1BRIZ datasheet, ADuM260N1BRIZ pinout, ADuM260N1BRIZ application, or ADuM260N1BRIZ equivalent, key selection criteria include reinforced insulation rating (VIORM = 849 V_PEAK), fail-safe output state configuration (N1 = low-fail-safe), wide-body SOIC_IC package creepage/clearance (8.7 mm), and AEC-Q100 qualification for automotive subsystems.

Technical Context

The ADuM260N1BRIZ implements six independent unidirectional CMOS-isolated channels using monolithic air-core transformers, enabling dc-correct operation without input transitions. Its architecture ensures tight channel-to-channel propagation delay matching (≤4.0 ns codirectional skew) and low jitter (70 ps rms).

It features dual-supply operation (VDD1/VDD2 = 1.7–5.5 V), undervoltage lockout (1.5 V/1.6 V thresholds), and fail-safe logic-low output state on input-side power loss - confirmed by N1 suffix per Ordering Guide and Truth Table in Rev. C datasheet.

Key Specifications

Pinout & Package

FAQ

What does the "N1" suffix indicate in ADuM260N1BRIZ?

The "N1" suffix in ADuM260N1BRIZ specifies the fail-safe output configuration: outputs default to logic low when the input-side supply (VDD1) is absent or below UVLO threshold. This behavior is defined in the Truth Table and Ordering Guide of the Rev. C datasheet and distinguishes it from the N0 variant (fail-high). The BRIZ suffix denotes the 16-lead wide-body SOIC_IC package with tape-and-reel packaging.

Does ADuM260N1BRIZ support 1.8 V operation on both sides of the isolation barrier?

Yes, ADuM260N1BRIZ supports 1.7 V to 5.5 V on both VDD1 and VDD2 supplies independently. Electrical Characteristics tables for 1.8 V operation (Table 7) confirm 15 ns max propagation delay, 150 Mbps data rate, and full functionality - enabling direct interfacing with 1.8 V FPGAs or microcontrollers on either side without level shifters.

Is ADuM260N1BRIZ certified for medical applications under IEC 60601-1?

Yes, ADuM260N1BRIZ is certified for IEC/CSA 60601-1 with reinforced insulation (2 MOPP) at 276 V_RMS, as listed in Table 11 of the Rev. C datasheet. Its 5.0 kV_RMS withstand voltage, 8.7 mm creepage, and VDE 0884-17 approval make it suitable for patient-connected medical devices requiring galvanic isolation between control and measurement circuits.

How does the common-mode transient immunity of ADuM260N1BRIZ compare to optocouplers?

ADuM260N1BRIZ achieves 100 kV/µs common-mode transient immunity - over 10× higher than typical optocouplers (5–10 kV/µs). This is enabled by iCoupler® transformer coupling, which rejects fast dv/dt noise without pulse distortion. The specification is verified per test conditions in Table 1 (|CMH|/|CML|) and directly improves reliability in motor drives with SiC/GaN switching.

Can ADuM260N1BRIZ be used in AEC-Q100 automotive applications?

Yes, ADuM260N1BRIZ is explicitly AEC-Q100 qualified for automotive applications, as stated in the "Automotive Products" section (page 27) and Regulatory Information (Table 11) of the Rev. C datasheet. It meets Grade 1 temperature range (−40°C to +125°C) and undergoes stress testing for humidity, thermal cycling, and ESD per AEC-Q100 Rev. G.
