Product details
Overview
ADUM4400ARIZ-RL from Analog Devices is a 5 kVRMS quad-channel digital isolator using iCoupler® transformer-based isolation, providing bidirectional signal transmission across an isolation barrier with 3.3 V/5 V level translation, 90 Mbps data rate, <2 ns pulse width distortion, and 25 kV/µs common-mode transient immunity for industrial motor drive control interfaces.
For engineers reviewing the ADUM4400ARIZ-RL datasheet, ADUM4400ARIZ-RL pinout, ADUM4400ARIZ-RL application, or ADUM4400ARIZ-RL equivalent, this page delivers verified specifications, safety-certified package details (RI-16), channel configuration (4-channel, all inputs on Side 1 / all outputs on Side 2), and real-world design implications for high-noise, high-voltage system partitioning.
Technical Context
The ADUM4400ARIZ-RL implements four independent unidirectional channels (A–D) with all inputs on Side 1 (pins 3–6) and all outputs on Side 2 (pins 11–14), enabling clean separation of controller-side logic from power-stage circuitry. It uses monolithic air-core transformers for galvanic isolation without LED degradation or timing drift.
Its patented refresh circuit ensures DC-correct output states during input inactivity or power-up/power-down transitions, while the output enable function (VE2 on pin 10) supports tri-state control of all Side 2 outputs - critical for bus arbitration and hot-swap compatibility in modular power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 90 Mbps (NRZ) - supports high-speed serial interfaces like SPI clock lines or PWM feedback loops without added latency. |
| Isolation Rating | 5000 VRMS for 1 minute - certified for reinforced insulation per UL 1577, IEC/EN/CSA 62368-1, and IEC/CSA 60601-1 (2 MOPP). |
| Pulse Width Distortion | ≤2 ns maximum - preserves duty cycle integrity in precision timing applications such as gate driver synchronization. |
| Common-Mode Transient Immunity | >25 kV/µs - maintains signal integrity during fast-switching events in IGBT/MOSFET half-bridge drivers. |
| Supply Voltage Range | 3.0 V to 5.5 V per side - enables mixed-voltage operation (e.g., 3.3 V MCU side / 5 V analog side) with built-in level translation. |
| Propagation Delay Skew | ≤2 ns (C grade) - ensures tight channel-to-channel timing alignment for parallel data paths or multi-phase control signals. |
| Quiescent Current | 0.57 mA per channel (input side, 5 V) - reduces standby power in battery-backed or energy-sensitive isolated sensor nodes. |
Pinout & Package
ADUM4400ARIZ-RL uses the RI-16 package: 16-lead SOIC wide-body enhanced creepage variant with 8.7 mm minimum creepage and clearance, rated for reinforced insulation up to 645 VPEAK per DIN EN IEC 60747-17 (VDE 0884-17).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VDD1 / VDD2 | Independent 3.0–5.5 V supplies for isolated sides - enables asymmetric voltage operation and eliminates need for external level shifters. |
| 2, 8, 9, 15 | GND1 / GND2 | Dedicated ground references per side - prevents ground-loop coupling and supports separate PCB ground planes. |
| 3–6 | VIA–VID | Four digital inputs on Side 1 - accepts standard CMOS logic levels; VIH = 2.0 V (5 V mode) or 1.6 V (3.3 V mode). |
| 11–14 | VOA–VOD | Four buffered CMOS outputs on Side 2 - VOH ≥ VDD2 − 0.4 V at 3.2 mA load, supporting direct interface to gate drivers or ADCs. |
| 10 | VE2 | Active-high output enable for all Side 2 outputs - allows dynamic disabling of outputs during fault conditions or sleep modes. |
| 7 | NC | No-connect pin - must remain unconnected per design; no internal bonding or routing. |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Eliminates LED aging and CTR degradation of optocouplers; achieves >50-year insulation lifetime under rated working voltage. |
| Output enable (VE2) | Tri-states all four Side 2 outputs within 8 ns - enables safe hot-plug insertion and prevents bus contention in distributed control systems. |
| DC-correct refresh circuit | Maintains valid output state during >1 µs input inactivity or power sequencing - essential for fail-safe operation in medical and industrial safety circuits. |
| System-level ESD enhancement | Meets IEC 61000-4-x standards (ESD/burst/surge) when used with proper PCB layout - reduces need for external TVS diodes on isolated data lines. |
| Mixed-voltage operation | Supports 3.3 V ↔ 5 V level translation across barrier without external components - simplifies interface between low-voltage microcontrollers and high-voltage peripherals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8640ED-IS | Capacitive isolation; 5 kVRMS; 100 Mbps; 4-channel unidirectional; 2.5 V to 5.5 V supply; no integrated refresh circuit. | Lacks DC-correct refresh - requires periodic input toggling to maintain output state; lower CMTI (20 kV/µs). | Prefer ADUM4400ARIZ-RL where guaranteed DC correctness and higher noise immunity are required in static-control applications. |

FAQ
What is the maximum data rate supported by ADUM4400ARIZ-RL?
ADUM4400ARIZ-RL supports a maximum data rate of 90 Mbps in NRZ format. This performance is specified for the C-grade version under recommended operating conditions (−40°C to +105°C, 3.0 V to 5.5 V supplies). At lower speeds (e.g., 10 Mbps), propagation delay and power consumption improve significantly - 18 ns typical tPLH/tPHL and 4.3 mA per channel at 5 V operation.
Does ADUM4400ARIZ-RL support mixed-voltage operation between input and output sides?
Yes, ADUM4400ARIZ-RL fully supports mixed-voltage operation: VDD1 and VDD2 can be independently set to 3.3 V or 5 V, enabling seamless level translation (e.g., 3.3 V MCU → 5 V gate driver). Input thresholds adapt automatically - VIH = 1.6 V at 3.3 V supply and 2.0 V at 5 V supply - ensuring reliable logic recognition across both domains.
What safety certifications apply to ADUM4400ARIZ-RL?
ADUM4400ARIZ-RL holds UL 1577 (5000 VRMS, 1 min), DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation (645 VPEAK), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1 approvals. The RI-16 package provides 8.7 mm creepage/clearance, satisfying stringent medical and industrial safety layout requirements.
How does the refresh feature in ADUM4400ARIZ-RL ensure DC correctness?
The ADUM4400ARIZ-RL incorporates a patented internal refresh circuit that periodically samples and retransmits the last valid input state across the isolation barrier - even when inputs are static or during power-up/down transitions. This guarantees deterministic output behavior without requiring external clocking or input toggling, unlike capacitive isolators that may drift or latch.
Can ADUM4400ARIZ-RL be used in high-temperature industrial environments?
Yes, ADUM4400ARIZ-RL is rated for continuous operation from −40°C to +105°C ambient temperature. Its thermal design supports junction temperatures up to 150°C under safety-limiting conditions (per VDE 0884-17), and its low quiescent current (0.57 mA per channel at 5 V) minimizes self-heating - making it suitable for enclosed motor drive cabinets and outdoor power conversion systems.
