Product details
Overview
ADUM241E1BRIZ from Analog Devices is a quad-channel digital isolator based on iCoupler® technology, providing 5.0 kVrms reinforced insulation, 150 Mbps guaranteed data rate, and 13 ns max propagation delay at 5 V operation. It supports 1.8 V to 5 V level translation across the isolation barrier and operates up to 125°C, enabling robust SPI/data converter isolation in industrial motor drives.
For engineers reviewing the ADUM241E1BRIZ datasheet, ADUM241E1BRIZ pinout, ADUM241E1BRIZ application, or ADUM241E1BRIZ equivalent, key selection criteria include its SOIC_W (RW-16) package with 7.8 mm creepage/clearance, fail-safe high output option, and backward compatibility with ADuM2400/ADuM2401/ADuM2402 pinouts for drop-in replacement in legacy designs.
Technical Context
The ADUM241E1BRIZ implements four independent unidirectional channels using monolithic air-core transformer coupling, ensuring dc-correct output states without input transitions. Its architecture delivers tight channel matching (≤3.0 ns codirectional skew) and low jitter (70 ps rms at 5 V), critical for synchronous serial interfaces.
It features dual supply domains (VDD1/VDD2), undervoltage lockout (1.5 V–1.6 V thresholds), and failsafe logic-high outputs when inputs are disabled-enabling safe system behavior during power-up/down or fault conditions in isolated gate driver control loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5.0 kVrms for 1 minute - meets reinforced insulation requirements per UL 1577, IEC/CSA 62368.1, and IEC 60601-1 (2 MOPP). |
| Data Rate | 150 Mbps maximum guaranteed - supports high-speed SPI, RS-485 transceiver control, and real-time feedback in servo drives. |
| Propagation Delay | 13 ns max at 5 V - enables precise timing alignment in closed-loop motor control and digital power management. |
| Common-Mode Transient Immunity | 100 kV/µs - maintains signal integrity in noisy industrial environments with fast-switching IGBTs or SiC MOSFETs. |
| Supply Voltage Range | 1.8 V to 5 V per side - allows direct interfacing with low-voltage MCUs (e.g., ARM Cortex-M0+) and 3.3 V/5 V peripherals without level shifters. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial ambient conditions without derating. |
| Fail-Safe Output | High-state default on input disable - ensures gate drivers remain off during MCU reset or communication loss, preventing shoot-through faults. |
Pinout & Package
ADUM241E1BRIZ uses a 16-lead RoHS-compliant SOIC_W (RW-16) wide-body package with 7.8 mm creepage and clearance, optimized for reinforced insulation in high-voltage systems. Pin 1–8 form the input-side domain (VDD1); pins 9–16 form the output-side domain (VDD2), with internal transformer isolation between domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (INA, INB, INC, IND) | Input data channels A–D | Accept CMOS-level signals from MCU or FPGA; support 1.8 V–5 V logic thresholds (VIH = 0.7×VDD1, VIL = 0.3×VDD1). |
| 5 (GND1) | Input-side ground reference | Return path for VDD1 domain; must be separated from GND2 by ≥7.8 mm PCB clearance to maintain isolation barrier integrity. |
| 6 (VDD1) | Input-side supply | Power source for input logic and transformers; UVLO triggers below 1.5 V to prevent metastable output states. |
| 7 (DISABLE1) | Input disable control | Pull-down enabled (9–15 µA) to force all outputs high when asserted; used for system-wide isolation shutdown. |
| 8 (VE2) | Output enable control | Pull-up enabled (−3 to −10 µA) to tri-state outputs when low; supports bus sharing in multi-master SPI configurations. |
| 9, 10, 11, 12 (OUTA, OUTB, OUTC, OUTD) | Output data channels A–D | Drive CMOS loads up to 4 mA; VOH ≥ VDD2 − 0.4 V at 4 mA ensures noise margin with downstream 3.3 V logic. |
| 13 (GND2) | Output-side ground reference | Return path for VDD2 domain; galvanically isolated from GND1; requires separate PCB plane with no copper bridges. |
| 14 (VDD2) | Output-side supply | Power source for output buffers and secondary transformer windings; supports independent voltage scaling (e.g., 3.3 V MCU ↔ 5 V actuator). |
| 15, 16 (NC) | No-connect terminals | Internally unused; must remain unconnected and unbonded per Analog Devices design guidelines to preserve isolation performance. |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Monolithic air-core transformers replace optocouplers, eliminating LED aging and enabling >50-year insulation lifetime per IEC 60747-17. |
| Backward pin compatibility | Direct replacement for ADuM2400/ADuM2401/ADuM2402 in existing layouts-no PCB rework required for upgrade to E1 variant. |
| Fail-safe high output | Outputs default to logic high when DISABLE1 is asserted or VDD1 is absent-critical for safety-critical gate driver enable/disable sequencing. |
| Low dynamic power | 0.01–0.02 mA/Mbps supply current scaling-reduces thermal load in densely packed industrial I/O modules. |
| High CMTI immunity | 100 kV/µs common-mode transient rejection-prevents false triggering in inverters with dV/dt > 50 kV/µs across motor windings. |

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 |
|---|---|---|---|
| ADUM241D1BRIZ | Fail-safe output is low (not high); identical pinout, timing, and isolation specs. | Preferred where default-off state is required for active-low enable inputs (e.g., certain gate drivers). | Select ADUM241D1BRIZ only if system logic requires low-state default on power loss or disable assertion. |
| SI8641ED-B-IS | Capacitive isolation; 5 kVrms, 150 Mbps, but 15 ns max propagation delay and 50 kV/µs CMTI. | Lower CMTI limits suitability in high-dV/dt SiC inverter applications; different pinout requires layout change. | Consider SI8641ED-B-IS only for cost-sensitive non-automotive designs where 50 kV/µs CMTI suffices and pinout redesign is acceptable. |
Compared with ADUM241D1BRIZ, ADUM241E1BRIZ provides fail-safe high outputs essential for gate driver safety interlocks; compared with SI8641ED-B-IS, it delivers superior 100 kV/µs CMTI and pin-compatible upgrade path from legacy ADuM240x designs without PCB revision.

FAQ
What is the maximum guaranteed data rate for ADUM241E1BRIZ?
The ADUM241E1BRIZ guarantees a maximum data rate of 150 Mbps across all operating voltages (1.8 V to 5 V) and temperatures (−40°C to +125°C). This specification is validated per test conditions in the datasheet with CL = 15 pF and CMOS signal levels. Higher rates may be achievable but are not production-guaranteed. The ADUM241E1BRIZ maintains this rate while delivering <3 ns channel matching and 70 ps rms jitter at 5 V, making it suitable for high-fidelity SPI and digital encoder interfaces.
Does ADUM241E1BRIZ support level translation between different supply voltages?
Yes, ADUM241E1BRIZ supports true bidirectional level translation: VDD1 can operate from 1.8 V to 5 V independently of VDD2, which also ranges from 1.8 V to 5 V. Input thresholds scale with VDD1 (VIH = 0.7×VDD1), and output drive strength adapts to VDD2 (VOH ≥ VDD2 − 0.4 V at 4 mA). This enables direct interfacing between a 1.8 V microcontroller and a 5 V isolated ADC or actuator without external level shifters-reducing BOM count and board space in compact industrial modules.
What safety certifications apply to ADUM241E1BRIZ?
ADUM241E1BRIZ holds UL 1577 (5000 Vrms, 1 min), IEC/CSA 62368.1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, CQC GB4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) approvals. Its RW-16 SOIC_W package achieves 7.8 mm creepage/clearance and 849 Vpeak reinforced insulation voltage, satisfying stringent requirements for medical, industrial, and automotive applications where patient or operator safety depends on isolation integrity.
How does the fail-safe output behavior work on ADUM241E1BRIZ?
ADUM241E1BRIZ features a fail-safe high output configuration: when DISABLE1 is pulled high or VDD1 drops below UVLO threshold (1.5 V), all four outputs (OUTA–OUTD) transition to and hold logic high. This behavior is hardwired in silicon and requires no external components. In motor drive applications, this ensures gate drivers remain disabled during MCU brownout or firmware crash-preventing hazardous shoot-through conditions. The ADUM241E1BRIZ datasheet specifies this as a guaranteed functional state, not a typical characteristic.
Is ADUM241E1BRIZ pin-compatible with earlier ADuM240x series devices?
Yes, ADUM241E1BRIZ is pin-compatible with ADuM2400/ADuM2401/ADuM2402 in the same RW-16 SOIC_W package. The pin assignments, supply domains (VDD1/GND1 vs. VDD2/GND2), and channel mapping (INA→OUTA, etc.) match exactly. This allows drop-in replacement in existing designs to upgrade from standard to fail-safe high output behavior without PCB modification-critical for maintaining legacy system certifications while improving functional safety compliance.
