Product details
Overview
ADUM4400CRIZ-RL from Analog Devices is a 4-channel, 5 kVRMS digital isolator in a 16-lead SOIC wide-body (RI-16) package, supporting bidirectional signal isolation at up to 90 Mbps with 3.3 V/5 V level translation across the barrier. It delivers 2 ns max pulse width distortion and 2 ns max channel-to-channel matching for precision timing-critical interfaces in medical equipment and motor drives.
For engineers reviewing the ADUM4400CRIZ-RL datasheet, ADUM4400CRIZ-RL pinout, ADUM4400CRIZ-RL application, or ADUM4400CRIZ-RL equivalent, this page provides verified specifications, safety-certified insulation parameters, real-world power consumption data at 1/10/90 Mbps, and validated alternative options for industrial and medical isolation designs.
Technical Context
The ADUM4400CRIZ-RL implements iCoupler® monolithic air-core transformer technology with integrated refresh circuitry to guarantee DC correctness during power-up, power-down, and static input conditions. Its dual-supply architecture supports independent 3.0–5.5 V operation on each side, enabling robust voltage translation between 3.3 V and 5 V domains without external level shifters.
All four channels are unidirectional (input-side A/B/C/D → output-side D/C/B/A), with dedicated output enable pins (VE1 on Side 1, VE2 on Side 2) providing high-impedance control per side. The device meets reinforced insulation requirements per DIN EN IEC 60747-17 (VDE 0884-17) and IEC/CSA 60601-1 (2 MOPP), with VIORM = 645 Vpeak and VISO = 5000 VRMS/1 min.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 90 Mbps (NRZ); enables high-speed serial bus isolation (e.g., SPI, RS-485 control lines) without timing bottlenecks. |
| Pulse Width Distortion | ≤2 ns (C grade); preserves duty cycle integrity for clock distribution and PWM feedback loops. |
| Channel Matching | ≤2 ns (C grade); ensures synchronized edge alignment across all four channels for multi-signal acquisition or drive control. |
| Common-Mode Transient Immunity | >25 kV/µs; maintains signal integrity in noisy motor drive and power supply environments with fast switching transients. |
| Supply Current @ 10 Mbps | 11.6 mA (Side 1) / 5.5 mA (Side 2) at 5 V; enables low-power isolated communication in battery-backed or thermally constrained systems. |
| Isolation Voltage | 5000 VRMS for 1 minute (UL 1577); certified for reinforced insulation in medical (IEC 60601-1, 2 MOPP) and industrial safety applications. |
| Operating Temperature | −40°C to +105°C; supports deployment in under-hood automotive subsystems and industrial motor controllers. |
Pinout & Package
ADUM4400CRIZ-RL uses a 16-lead SOIC wide-body package with enhanced creepage (RI-16), featuring 8.7 mm minimum creepage and clearance between input and output sides per IEC 60601-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VDD1 / VDD2 | Independent 3.0–5.5 V supplies for isolated input (Side 1) and output (Side 2) domains; enables level translation. |
| 2, 8, 9, 15 | GND1 / GND2 | Separate ground references per side; mandatory physical separation prevents ground loop coupling. |
| 3–6 | VIA–VID | Unidirectional logic inputs on Side 1; accept CMOS levels compatible with 3.3 V or 5 V microcontrollers. |
| 10 | VE2 | Active-high output enable for Side 2 outputs; allows dynamic tri-state control of isolated signals during system sleep or fault recovery. |
| 11–14 | VOD–VOA | Unidirectional logic outputs on Side 2; drive 3.3 V or 5 V loads with 3.2 mA sink/source capability. |
| 7 | NC | No-connect pin; must remain unconnected per design to avoid parasitic coupling or thermal stress. |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Monolithic air-core transformers replace LEDs and photodiodes, eliminating LED aging and enabling 50-year lifetime reliability. |
| Patented refresh circuitry | Maintains correct DC output state during power transitions and static input conditions-no external watchdog or refresh signals required. |
| Input glitch filter | Rejects sub-10 ns noise pulses on input lines, preventing false triggering in EMI-heavy environments like motor drives. |
| System-level ESD enhancement | Designed for IEC 61000-4-x compliance (ESD/burst/surge); board layout determines final system-level pass/fail margin. |
| Dual-supply voltage translation | Supports 3.3 V ↔ 5 V signal bridging across isolation barrier without external level shifters or resistive dividers. |

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 | 4-channel, 5 kVRMS, capacitive isolation; 150 Mbps max; no output enable pin; VIORM = 600 Vpeak. | Lacks VE2 control; unsuitable where dynamic tri-state of isolated outputs is required (e.g., shared bus arbitration). | Select when higher speed (≥100 Mbps) is critical and output enable functionality is not needed. |
| ISO6740QDWR | 4-channel, 5 kVRMS, capacitive isolation; 50 Mbps max; 3.3 V only; VIORM = 600 Vpeak; no refresh circuitry. | Requires external DC restoration for static signals; limited to 3.3 V systems; lower speed ceiling restricts use in high-bandwidth control loops. | Select for cost-sensitive 3.3 V-only designs where 50 Mbps suffices and DC correctness is managed externally. |
Compared with SI8640ED-B-IS and ISO6740QDWR, ADUM4400CRIZ-RL uniquely combines output enable control, guaranteed DC correctness via refresh, and C-grade timing performance (≤2 ns PWD/channel match) - making it optimal for medical and motor control applications demanding deterministic behavior under power transients and static conditions.

FAQ
What is the maximum data rate supported by ADUM4400CRIZ-RL?
ADUM4400CRIZ-RL supports a maximum data rate of 90 Mbps in NRZ format. This specification applies to the C-grade version and is validated under load conditions of CL = 15 pF and CMOS signal levels. At lower speeds (e.g., 10 Mbps), the device consumes significantly less power-11.6 mA on Side 1 and 5.5 mA on Side 2 at 5 V operation-making it suitable for both high-speed and low-power isolation needs within the same design.
Does ADUM4400CRIZ-RL support level translation between 3.3 V and 5 V domains?
Yes, ADUM4400CRIZ-RL supports true bidirectional level translation: VDD1 can operate from 3.0 V to 5.5 V independently of VDD2, which also ranges from 3.0 V to 5.5 V. This allows direct interfacing between 3.3 V microcontrollers and 5 V peripherals across the isolation barrier without external level-shifting components. Input thresholds (VIH = 2.0 V min at 5 V, 1.6 V min at 3.3 V) and output drive strength (3.2 mA) are specified for both supply configurations.
What safety certifications does ADUM4400CRIZ-RL hold?
ADUM4400CRIZ-RL carries UL 1577 (5000 VRMS/1 min), DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation (VIORM = 645 Vpeak), IEC/CSA 60601-1 (2 MOPP), IEC/EN/CSA 62368-1, and IEC/CSA 61010-1 approvals. These certifications apply specifically to the RI-16 package variant and validate its suitability for medical, industrial, and test equipment where reinforced isolation and high working voltage endurance are mandated.
How does the refresh feature in ADUM4400CRIZ-RL ensure DC correctness?
The patented refresh circuitry in ADUM4400CRIZ-RL continuously monitors static input states and injects periodic pulses across the isolation barrier to maintain correct output logic levels-even during prolonged periods of no input transition or during power-up/power-down sequences. This eliminates the need for external refresh clocks or watchdog timers, ensuring reliable DC signal integrity in applications such as enable/disable control lines and fault status reporting.
Can ADUM4400CRIZ-RL be used in high-temperature environments like motor drives?
Yes, ADUM4400CRIZ-RL is rated for operation from −40°C to +105°C ambient temperature and features thermal derating curves compliant with DIN EN IEC 60747-17. Its SOIC RI-16 package provides low thermal resistance (θJCO = 28°C/W), enabling reliable deployment in under-hood automotive subsystems and industrial motor drive inverters where junction temperatures may approach 125°C under sustained load.
