Product details
Overview
ADUM4400CRIZ from Analog Devices is a 5 kVRMS quad-channel digital isolator using iCoupler® transformer-based technology, providing bidirectional signal isolation across two independent supply domains (3.0–5.5 V). It delivers 90 Mbps data rate, <2 ns pulse width distortion, and 25 kV/µs common-mode transient immunity, enabling robust communication in high-noise industrial motor drives and medical equipment interfaces.
For engineers reviewing the ADUM4400CRIZ datasheet, ADUM4400CRIZ pinout, ADUM4400CRIZ application, or ADUM4400CRIZ equivalent, this page provides verified specifications, SOIC-16 RW-16 package details, functional channel mapping, safety-certified insulation parameters, and real-world design implications for isolated SPI, RS-485, and gate driver control circuits.
Technical Context
The ADUM4400CRIZ implements four unidirectional, input-to-output channels with side-specific output enable (VE1/VE2), supporting mixed-voltage operation (3.3 V/5 V or 5 V/3.3 V) without level-shifting circuitry. Its monolithic air-core transformer architecture eliminates LED aging and timing drift inherent in optocouplers.
It features patented refresh logic ensuring DC-correct output during power-up, power-down, or static input conditions, and includes input glitch filtering to suppress sub-10 ns noise transients. All channels meet reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 Vpeak and 5000 VRMS withstand rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 90 Mbps (NRZ) - supports high-speed isolated SPI, CAN FD physical layer signaling, and real-time control loops. |
| Isolation Rating | 5000 VRMS for 1 minute - certified for reinforced insulation in medical (2 MOPP) and industrial safety-critical systems. |
| Pulse Width Distortion | <2 ns maximum - ensures precise edge alignment across all four channels for time-critical feedback paths. |
| Common-Mode Transient Immunity | >25 kV/µs - maintains signal integrity during fast-switching events in motor inverters and SMPS gate drive circuits. |
| Supply Voltage Range | 3.0 V to 5.5 V per side - enables direct interfacing with 3.3 V microcontrollers and 5 V legacy peripherals across the barrier. |
| Propagation Delay Skew | <10 ns (C grade) - guarantees synchronized timing between isolated control signals in multi-phase power converters. |
| Quiescent Current | 0.57 mA/channel (input side, 5 V) - reduces standby power in battery-backed or energy-sensitive isolated sensors. |
Pinout & Package
ADUM4400CRIZ uses a 16-lead SOIC wide-body package (RW-16) with 7.8 mm minimum creepage/clearance, rated for reinforced insulation per IEC 62368-1 and IEC 60601-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, Pin 1 | Input-side supply | 3.0–5.5 V power for Side 1 logic and transformers; decoupling capacitor required within 1 cm. |
| GND1, Pins 2 & 8 | Input-side ground reference | Low-impedance return path for Side 1; must be separated from GND2 by ≥7.8 mm on PCB. |
| VIA–VID, Pins 3–6 | Logic inputs (A–D) | CMOS-compatible inputs accepting 3.3 V or 5 V logic; VIH = 2.0 V (5 V mode), VIH = 1.6 V (3.3 V mode). |
| NC, Pin 7 | No connect | Internally unused; must remain unconnected and unstubbed on PCB layout. |
| GND2, Pins 9 & 15 | Output-side ground reference | Isolated return for Side 2; forms safety barrier with GND1; requires separate plane partitioning. |
| VE2, Pin 10 | Output enable (Side 2) | Active-high control: VOA–VOD go high-Z when VE2 = low; critical for bus arbitration and hot-swap isolation. |
| VOD–VOA, Pins 11–14 | Logic outputs (D–A) | Push-pull CMOS outputs driving 3.3 V or 5 V loads; VOL ≤ 0.4 V @ 3.2 mA ensures TTL/CMOS compatibility. |
| VDD2, Pin 16 | Output-side supply | Independent 3.0–5.5 V rail for Side 2; enables voltage translation (e.g., 5 V MCU → 3.3 V FPGA). |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Eliminates optocoupler LED degradation and temperature-dependent CTR drift; supports >50-year insulation lifetime at rated voltage. |
| Output enable (VE2) | Allows dynamic disabling of all four outputs to prevent bus contention in shared isolated communication lines (e.g., isolated I²C or UART). |
| Mixed-voltage operation | Supports 3.3 V/5 V or 5 V/3.3 V cross-barrier signaling without external level shifters-reduces BOM count and layout area. |
| System-level ESD enhancement | Designed to meet IEC 61000-4-x standards (ESD/burst/surge); performance depends on board layout per AN-793. |
| Refresh logic | Maintains correct DC output state during prolonged input inactivity or asymmetric power sequencing-critical for fail-safe control systems. |
Applications
| Industrial Motor Drives | Medical Imaging Power Supplies |

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-B-IS | Capacitive isolation; 5000 VRMS, 100 Mbps, but only 10 kV/µs CMTI and no output enable pin. | Lacks VE2 control; unsuitable for bus-arbitrated systems requiring dynamic output disable. | Select when higher data rate is prioritized over CMTI and output control; verify layout for lower noise immunity. |
| ISO6740QDWR | Capacitive isolation; 5000 VRMS, 50 Mbps, integrated 3.3 V LDO on side 2, no output enable. | Includes regulator but sacrifices speed and disable functionality; VIORM = 425 Vpeak (lower than ADUM4400CRIZ's 645 Vpeak). | Choose when side-2 power regulation is needed and 50 Mbps suffices; not suitable for 2 MOPP medical designs. |
Compared with SI8640ED-B-IS and ISO6740QDWR, ADUM4400CRIZ offers superior common-mode noise rejection and active output control-critical for motor control and medical power systems-while maintaining identical safety certification scope and SOIC-16 footprint.

FAQ
What is the maximum data rate supported by ADUM4400CRIZ?
ADUM4400CRIZ supports up to 90 Mbps in NRZ format, validated across all operating conditions (−40°C to +105°C) and supply configurations (3.3 V/3.3 V, 5 V/5 V, or mixed 3.3 V/5 V). This enables use in high-speed isolated serial interfaces such as SPI clock domains exceeding 45 MHz and real-time control loops with sub-100 ns latency requirements. The C-grade device guarantees <2 ns pulse width distortion at this rate.
Does ADUM4400CRIZ support level translation between different supply voltages?
Yes, ADUM4400CRIZ natively supports bidirectional level translation: its input side (VDD1) and output side (VDD2) operate independently from 3.0 V to 5.5 V. For example, it can translate 5 V logic inputs on Side 1 to 3.3 V outputs on Side 2-or vice versa-without external components. This is confirmed in Tables 7 and 10 of the datasheet for mixed-voltage operation modes.
What safety certifications apply to ADUM4400CRIZ?
ADUM4400CRIZ holds UL 1577 (5000 VRMS), DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation (VIORM = 645 Vpeak), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1 approvals. These are explicitly listed for the RW-16 package in Table 14 and validated per test methods in Table 16 of the Rev. G datasheet.
How does the output enable (VE2) function work on ADUM4400CRIZ?
VE2 (Pin 10) is an active-high enable signal for all four outputs (VOA–VOD) on Side 2. When VE2 = high or open, outputs follow their respective inputs (VIA–VID); when VE2 = low, all outputs enter high-impedance state within 8 ns. This feature is essential for bus sharing, hot-swap isolation, and preventing contention in multi-master isolated networks.
Is ADUM4400CRIZ pin-compatible with other members of the ADuM440x family?
No-ADUM4400CRIZ has a unique pinout optimized for four input/four output unidirectional channels (VIA–VID inputs on Side 1, VOA–VOD outputs on Side 2). ADUM4401 and ADUM4402 feature different channel directionality (e.g., mixed input/output per side) and distinct VE1/VE2 placement. Pin compatibility is not claimed in the datasheet; each variant requires dedicated PCB layout.
