Analog Devices Inc. ADUM262N1BRIZ

Overview

ADUM262N1BRIZ from Analog Devices is a 6-channel, 5.0 kV_RMS reinforced digital isolator using iCoupler® technology, with 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and fail-safe high output configuration. It enables robust SPI/data converter isolation in industrial PLCs and motor drives operating up to 125°C.

For engineers reviewing the ADUM262N1BRIZ datasheet, ADUM262N1BRIZ pinout, ADUM262N1BRIZ application, or ADUM262N1BRIZ equivalent, key selection criteria include its 849 V_PEAK VIORM rating, 100 kV/µs common-mode transient immunity, AEC-Q100 qualification, and 1.8 V–5.5 V dual-supply voltage translation capability across the isolation barrier.

Technical Context

The ADUM262N1BRIZ implements monolithic air-core transformer-based isolation with independent CMOS input/output stages on each side, supporting asymmetric supply operation (e.g., 1.8 V on side 1, 5 V on side 2). Its fail-safe high logic ensures outputs default to logic high when input-side power is absent.

Propagation delay matching is tightly controlled at ≤4.0 ns (codirectional) and ≤4.5 ns (opposing direction), enabling precise timing in multichannel synchronous interfaces like isolated SPI buses. The device meets reinforced insulation requirements per DIN EN IEC 60747-17 (VDE 0884-17) and IEC/CSA 60601-1 (2 MOPP).

FAQ

What is the fail-safe output state of ADUM262N1BRIZ?

The ADUM262N1BRIZ has a fail-safe high output configuration: when the input-side power supply (VDD1) is absent or below UVLO threshold, all six output channels (A–F) default to logic high. This behavior is confirmed in the datasheet's Functional Block Diagram (Figure 3) and Truth Table section, ensuring predictable control-state behavior during power-up, brownout, or fault conditions in the ADUM262N1BRIZ.

Does ADUM262N1BRIZ support level translation between 1.8 V and 5 V logic?

Yes, ADUM262N1BRIZ supports true bidirectional level translation: VDD1 can operate from 1.7 V to 5.5 V independently of VDD2, which also ranges from 1.7 V to 5.5 V. Electrical Characteristics tables confirm valid operation at 1.8 V/5 V combinations, with input thresholds scaling to 0.7×VDDx and output drive meeting VOH/VOL specs across both rails - a core design feature of the ADUM262N1BRIZ.

What safety certifications does ADUM262N1BRIZ hold?

ADUM262N1BRIZ is certified to UL 1577 (5000 V_RMS, 1 min), DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation (849 V_PEAK VIORM), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, and CQC GB 4943.1. These approvals are explicitly listed in Table 11 of the ADUM262N1BRIZ datasheet Rev. C.

How does ADUM262N1BRIZ achieve 100 kV/µs common-mode transient immunity?

ADUM262N1BRIZ achieves 100 kV/µs CMTI via its monolithic air-core transformer isolation architecture and balanced differential input stage, which rejects fast common-mode edges on the isolation barrier. This value is measured per IEC 60747-17 Annex D with 800 V transient magnitude at 1000 V common-mode bias, and is specified in Tables 1–4 under AC Specifications - a defining performance metric of the ADUM262N1BRIZ.

Is ADUM262N1BRIZ pin-compatible with other ADuM26xN variants?

No - ADUM262N1BRIZ is not pin-compatible with ADUM260N/ADUM261N/ADUM263N. While all share the same 16-lead SOIC_IC package and pin count, the channel directionality (input/output assignment) and fail-safe logic differ. Pin Configurations and Function Descriptions (page 18) show ADUM262N1BRIZ assigns Pins 1–6 as inputs and Pins 9–14 as outputs - a fixed mapping unique to the ADUM262N1BRIZ variant.
