Product details
Overview
ADUM240E1BRWZ from Analog Devices is a quad-channel, 5.0 kVrms digital isolator using iCoupler® technology, designed for high-noise industrial and medical systems requiring galvanic signal separation between microcontrollers and isolated peripherals. It delivers 150 Mbps data rate, 13 ns max propagation delay at 5 V, and operates across 1.8 V to 5 V supply rails with fail-safe high output configuration.
For engineers reviewing the ADUM240E1BRWZ datasheet, ADUM240E1BRWZ pinout, ADUM240E1BRWZ application, or ADUM240E1BRWZ equivalent, key selection criteria include reinforced insulation (849 Vpeak VIORM), 100 kV/µs common-mode transient immunity, SOIC_W-16 package creepage (7.8 mm), and backward compatibility with ADUM2400-series footprints.
Technical Context
The ADUM240E1BRWZ implements four independent unidirectional isolation channels using monolithic air-core transformers, ensuring dc-correct output states without input transitions. Its architecture supports asymmetric voltage translation-e.g., 1.8 V logic on side 1 and 5 V logic on side 2-enabling interoperability across mixed-voltage subsystems.
It features two enable inputs (VE2, DISABLE1) for channel control and tristate outputs, with undervoltage lockout (UVLO) thresholds of 1.5 V/1.6 V per side. Fail-safe behavior defaults to high output when input power is absent or disabled, satisfying IEC 60601-1 and IEC 61010-1 safety requirements for medical and test equipment.

Pinout & Package
ADUM240E1BRWZ uses a 16-lead wide-body SOIC (RW-16) package with input-side pins (1–8) physically and electrically isolated from output-side pins (9–16). Creepage and clearance distances meet IEC 60601-1 and IEC 62368-1 requirements for reinforced insulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Input-side power and ground | Supplies logic for channels A–D inputs; supports 1.8–5 V operation independently of VDD2 |
| VDD2, GND2 | Output-side power and ground | Supplies logic for channels A–D outputs; enables bidirectional voltage translation across isolation barrier |
| INA, INB, INC, IND | Input data signals | Unidirectional CMOS-compatible inputs accepting 1.8–5 V logic; no external pull-ups required |
| OUTA, OUTB, OUTC, OUTD | Isolated output signals | Fail-safe high outputs when input power lost or DISABLE1 asserted; drive 4 mA loads at VDD2 − 0.4 V |
| VE2 | Output enable (active-low) | Pull-up internal to VDD2; asserts tristate on all outputs when driven low; used for bus arbitration or power sequencing |
| DISABLE1 | Input disable (active-high) | Pull-down internal to GND1; forces inputs to logic low when driven high; prevents spurious switching during power-up |

Use Scenario: Galvanically isolating SPI bus between host MCU and isolated precision ADC (e.g., AD7768) in weigh scales or energy meters. IC Role / Device Role / Timing Role: Bidirectional SPI clock/data isolation with independent 1.8 V (MCU) and 3.3 V (ADC) rail support. Use Value: 150 Mbps capability exceeds standard SPI speeds (e.g., 20 MHz SCLK × 2 edges = 40 Mbps), enabling oversampling and real-time diagnostics. |
| Medical Patient Monitoring | Automotive Battery Management Systems |
Use Scenario: Isolating ECG front-end analog signal paths and digital control lines in Class II patient-connected devices. IC Role / Device Role / Timing Role: Reinforced insulation barrier meeting IEC 60601-1 2 MOPP requirements for patient-side sensor interfaces and microcontroller communication. Use Value: 849 Vpeak VIORM and 5.0 kVrms withstand voltage satisfy creepage/clearance mandates for 250 Vrms working voltage applications. |
Use Scenario: Isolating cell voltage monitoring ICs (e.g., LTC6813) from main BMS controller in 400–800 V EV battery packs. IC Role / Device Role / Timing Role: High-CMTI isolation of UART/SPI telemetry and fault reporting lines across 400+ V potential differences. Use Value: 100 kV/µs common-mode immunity prevents false fault triggers during rapid pack switching transients (e.g., contactor closure). |
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 |
|---|---|---|---|
| ADUM240D1BRWZ | Fail-safe low output (vs. high on ADUM240E1BRWZ); identical timing, isolation, and package | Required where default logic-low state is needed for safety shutdown or active-low enable schemes | Select ADUM240D1BRWZ only if system logic requires de-asserted default output; otherwise ADUM240E1BRWZ maintains compatibility with ADUM2400-series designs. |
| SI8641ED-B-IS | Capacitive isolation; 5 kVrms, 150 Mbps, but lower CMTI (75 kV/µs) and no AEC-Q100 qualification | Suitable for cost-sensitive industrial controls but not medical or automotive due to missing 2 MOPP and Grade 1 validation | Choose SI8641ED-B-IS for non-safety-critical 3.3 V-only systems; ADUM240E1BRWZ remains preferred for regulated environments demanding VDE 0884-17 and IEC 60601-1 compliance. |
Compared with ADUM240D1BRWZ, ADUM240E1BRWZ provides fail-safe high output essential for active-high enable architectures, while SI8641ED-B-IS lacks the reinforced insulation certification and automotive qualification required for BMS and patient monitoring deployments.

FAQ
What is the maximum guaranteed data rate for ADUM240E1BRWZ?
The ADUM240E1BRWZ guarantees a data rate of 150 Mbps across its full operating temperature range (−40°C to +125°C) and supply voltage range (1.8 V to 5 V). This specification is verified per Table 1 through Table 7 in the Rev. E datasheet and applies to all four channels simultaneously under CL = 15 pF loading conditions.
Does ADUM240E1BRWZ support level translation between different supply voltages?
Yes, ADUM240E1BRWZ 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. This allows direct interfacing between a 1.8 V microcontroller and a 3.3 V isolated ADC or 5 V gate driver without external level shifters.
What safety certifications does ADUM240E1BRWZ hold?
ADUM240E1BRWZ is certified to UL 1577 (5000 Vrms), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation (849 Vpeak VIORM), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1. These approvals are documented in Tables 12 and 13 of the Rev. E datasheet.
How does the fail-safe behavior of ADUM240E1BRWZ function?
ADUM240E1BRWZ defaults to logic high on all outputs (OUTA–OUTD) when VDD1 is unpowered or when DISABLE1 is asserted high. This fail-safe high state is hardwired in silicon and does not require external components, ensuring predictable behavior during power loss or initialization faults in safety-critical systems.
Is ADUM240E1BRWZ pin-compatible with earlier ADUM2400-series isolators?
Yes, ADUM240E1BRWZ is pin-compatible with ADUM2400, ADUM2401, and ADUM2402 in the same RW-16 SOIC package. The pin assignments, footprint, and thermal characteristics match exactly, enabling drop-in upgrades without PCB redesign or layout modification.
