Product details

Overview

ADUM4402ARWZ-RL from Analog Devices is a 5 kV_RMS quad-channel digital isolator with bidirectional communication, 3.3 V/5 V level translation, and output enable functionality. It delivers 90 Mbps data rate, <2 ns pulse width distortion, and operates across −40°C to +105°C in medical equipment and motor drive interfaces.

For engineers reviewing the ADUM4402ARWZ-RL datasheet, ADUM4402ARWZ-RL pinout, ADUM4402ARWZ-RL application, or ADUM4402ARWZ-RL equivalent, this page provides verified specifications, SOIC-Wide (RW-16) package details, IEC 62368-1/60601-1 safety compliance, and real-world isolation design context for high-noise industrial systems.

Technical Context

The ADUM4402ARWZ-RL implements iCoupler® monolithic air-core transformer technology across four independent channels, enabling galvanic isolation without optocoupler aging or LED degradation. Its dual-supply architecture supports asymmetric operation (e.g., 3.3 V on Side 1, 5 V on Side 2), with integrated input glitch filtering and patented refresh circuitry ensuring DC correctness during power-up and signal inactivity.

It features side-specific output enable (VE1 on Side 1, VE2 on Side 2), precise timing control (≤2 ns channel-to-channel matching), and >25 kV/µs common-mode transient immunity-critical for gate driver feedback loops and isolated ADC interfaces in switching power supplies.

Pinout & Package

ADUM4402ARWZ-RL uses a 16-lead SOIC wide-body (RW-16) package with 7.8 mm minimum creepage and clearance, optimized for reinforced insulation in space-constrained designs.

Pin/Terminal	Circuit Role	Design Meaning
1, 16	VDD1 / VDD2	Independent supply pins for isolated sides; support 3.0–5.5 V, enabling voltage translation across barrier.
2, 8, 9, 15	GND1 / GND2	Dedicated ground references per side; mandatory separation prevents ground-loop coupling and preserves CM rejection.
3–6	VIA–VID	Four logic inputs on Side 1; accept standard CMOS levels (VIH = 2.0 V @ 5 V, 1.6 V @ 3.3 V).
10	VE2	Active-high output enable for Side 2 outputs; drives VOA–VOD into high-impedance when low-enables bus sharing.
11–14	VOD–VOA	Four logic outputs on Side 2; deliver rail-to-rail CMOS-compatible signals with VOL ≤ 0.4 V @ 3.2 mA load.

Key Features

Feature	Design Value
Bidirectional Channel Configuration	Inputs on Side 1 (VIA–VID), outputs on Side 2 (VOA–VOD); supports master-slave isolation in isolated UART/SPI links.
Output Enable Functionality	VE2 pin controls all Side 2 outputs; allows dynamic bus arbitration and reduces EMI during idle periods.
System-Level ESD Hardening	Enhanced layout and circuit design meet IEC 61000-4-x requirements; reduces need for external TVS diodes in medical front-ends.
DC-Correct Refresh Architecture	Patented internal refresh ensures output state retention during prolonged input inactivity or power sequencing events.
Mixed-Voltage Operation	Validated 3.3 V/5 V, 5 V/3.3 V, and same-voltage configurations; eliminates level-shifter ICs in multi-rail systems.

FAQ

What is the maximum data rate supported by ADUM4402ARWZ-RL?

The ADUM4402ARWZ-RL supports a maximum data rate of 90 Mbps in NRZ format, validated across all operating voltages (3.3 V and 5 V) and temperature ranges (−40°C to +105°C). This rating applies to each of its four isolated channels independently and is specified with ≤2 ns pulse width distortion to ensure signal integrity in high-speed serial interfaces like isolated SPI and digital encoder links.

Does ADUM4402ARWZ-RL support mixed-voltage operation between input and output sides?

Yes, ADUM4402ARWZ-RL fully supports mixed-voltage operation: it is characterized for 3.3 V/5 V (Side 1/Side 2), 5 V/3.3 V, and same-voltage configurations. Electrical specifications-including propagation delay, supply current, and logic thresholds-are explicitly provided in the datasheet for each mode, enabling robust level translation without external components in systems such as 3.3 V microcontrollers interfacing to 5 V field buses.

What safety certifications does ADUM4402ARWZ-RL hold?

ADUM4402ARWZ-RL holds UL 1577 (5000 V_RMS, 1 min), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) approvals. These cover reinforced insulation up to 645 V_PEAK and validate suitability for medical, industrial, and consumer safety-critical applications without additional system-level certification burden.

How does the output enable (VE2) function work on ADUM4402ARWZ-RL?

The VE2 pin on ADUM4402ARWZ-RL is an active-high enable for all Side 2 outputs (VOA–VOD). When VE2 is high or left unconnected, outputs reflect their respective input states. When VE2 is driven low, all Side 2 outputs enter high-impedance state-enabling shared-bus architectures and reducing standby power. Propagation delay from VE2 transition to output disable/enable is ≤8 ns, ensuring fast bus arbitration in real-time control systems.

What is the common-mode transient immunity (CMTI) specification for ADUM4402ARWZ-RL?

ADUM4402ARWZ-RL guarantees >25 kV/µs common-mode transient immunity, tested per IEC 61000-4-x with 1000 V common-mode step and 800 V transient magnitude. This performance is maintained across the full operating temperature range and enables reliable operation in high-noise environments such as variable-frequency drives, where fast-switching IGBTs induce large dV/dt across isolation barriers.
