Analog Devices Inc. ADUM2400ARWZ-RL

Overview

ADUM2400ARWZ-RL from Analog Devices is a quad-channel digital isolator based on iCoupler® transformer technology, providing galvanic isolation between microcontroller I/O and high-voltage subsystems in industrial motor drives and medical equipment. It supports bidirectional communication, 3 V/5 V level translation, operates up to 105°C, and delivers 1 Mbps maximum data rate with 100 ns max propagation delay and 40 ns pulse width distortion.

For engineers reviewing the ADUM2400ARWZ-RL datasheet, ADUM2400ARWZ-RL pinout, ADUM2400ARWZ-RL application, or ADUM2400ARWZ-RL equivalent, key selection criteria include its 1 Mbps data rate, SOIC-16 wide-body package (RW-16), 5000 V_rms isolation rating, and compatibility with mixed 3 V/5 V supply domains across the isolation barrier.

Technical Context

The ADUM2400ARWZ-RL implements four independent unidirectional isolation channels using monolithic air-core transformers and high-speed CMOS interface circuitry. Its architecture eliminates optocoupler limitations-no LED aging, no CTR drift, and no temperature-dependent nonlinearities-while enabling precise timing control via integrated refresh logic for DC correctness during idle or power transitions.

All channels support independent supply domains (VDD1 = 2.7–5.5 V, VDD2 = 2.7–5.5 V), allowing true 3 V/5 V level translation. The device features output enable functionality, 25 kV/µs common-mode transient immunity, and guaranteed pulse width distortion ≤40 ns at 1 Mbps, making it suitable for noise-sensitive isolated feedback and safety-critical signal routing.

FAQ

What is the maximum data rate supported by ADUM2400ARWZ-RL?

ADUM2400ARWZ-RL supports a maximum data rate of 1 Mbps, as verified in the Rev. H datasheet Table 1 and Table 2 under "Maximum Data Rate" for the ARWZ grade. This rating is guaranteed with ≤40 ns pulse width distortion and applies across the full operating temperature range (−40°C to +105°C) and supply ranges (2.7–5.5 V per side).

Does ADUM2400ARWZ-RL support level translation between 3 V and 5 V domains?

Yes, ADUM2400ARWZ-RL supports true bidirectional level translation: VDD1 may operate from 2.7–5.5 V independently of VDD2 (also 2.7–5.5 V). The datasheet confirms compatible logic thresholds (VIH = 2.0 V at 5 V, VIH = 1.6 V at 3 V) and output drive capability (VOH/VOL specified across both rails), enabling direct interconnection of 3.3 V microcontrollers and 5 V peripherals.

What safety certifications apply to ADUM2400ARWZ-RL?

ADUM2400ARWZ-RL holds UL 1577 (5000 V_rms/1 min), IEC/EN/CSA 62368-1, IEC/CSA 60601-1, IEC/CSA 61010-1, CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) certifications. These are explicitly listed in the "Regulatory Information" section of the Rev. H datasheet and apply to the RW-16 package variant.

Is output enable (OE) functionality available on ADUM2400ARWZ-RL?

Yes, ADUM2400ARWZ-RL includes an active-low output enable (OE) pin (Pin 15), documented in the "Pin Configurations and Function Descriptions" section (page 16) and switching specifications table. When OE is low, outputs B1–B4 enter high-impedance state; propagation delays for enable/disable are specified as 6–8 ns.

What is the common-mode transient immunity (CMTI) performance of ADUM2400ARWZ-RL?

ADUM2400ARWZ-RL achieves >25 kV/µs common-mode transient immunity at both logic high and low output states, as measured per datasheet test condition (VCM = 1000 V, transient magnitude = 800 V). This value is consistent across 3 V, 5 V, and mixed-supply operation and is critical for noise resilience in motor drive and power supply applications.
