Product details
Overview
ADUM140D1BRWZ from Analog Devices is a quad-channel digital isolator based on iCoupler® transformer technology, providing 3.75 kVRMS reinforced isolation in a wide-body SOIC-16 package. It delivers 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and operates across 1.8 V to 5 V supply rails with level translation capability. It is used in industrial SPI isolation, motor drive control interfaces, and medical equipment signal conditioning where high noise immunity and safety compliance are critical.
For engineers reviewing the ADUM140D1BRWZ datasheet, ADUM140D1BRWZ pinout, ADUM140D1BRWZ application, or ADUM140D1BRWZ equivalent, this page provides verified specifications including CMTI (100 kV/µs), fail-safe output configuration, AEC-Q100 qualification, UL/VDE/IEC safety certifications, and SOIC_W package dimensions - all essential for high-reliability isolated interface design.
Technical Context
The ADUM140D1BRWZ implements four independent unidirectional isolation channels using monolithic air-core transformers, enabling dc-correct transmission without input transitions. Its architecture supports asymmetric supply operation (e.g., 1.8 V side A / 5 V side B) and includes integrated undervoltage lockout (UVLO) with 1.6 V threshold and 0.1 V hysteresis on both sides.
It features two enable inputs (VE1, VE2) and one disable input (DISABLE1), allowing selective channel activation and tristate output control. The device guarantees tight channel matching (≤3.0 ns codirectional skew) and low jitter (70 ps rms at 5 V), making it suitable for timing-critical serial protocols like isolated SPI and RS-485 transceiver control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3.75 kVRMS for 1 minute - meets reinforced insulation requirements per IEC/EN/CSA 60950-1, 60601-1, and 61010-1 |
| Data Rate | 150 Mbps maximum guaranteed - supports high-speed SPI, digital encoder, and real-time control loop interfaces |
| Propagation Delay | 13 ns max at 5 V - enables sub-20 ns round-trip latency in bidirectional isolated links |
| CMTI | 100 kV/µs minimum - ensures robust operation in high-dv/dt environments such as motor drives and inverters |
| Supply Voltage Range | 1.8 V to 5 V per side - allows voltage translation between legacy 3.3 V logic and modern 1.8 V microcontrollers |

| Fail-Safe Output | High-fail option - outputs default to logic high when input power is lost or disabled, preventing undefined states in safety-critical paths |
Pinout & Package
ADUM140D1BRWZ is housed in a 16-lead RoHS-compliant wide-body SOIC (SOIC_W, RW-16) package with 7.8 mm creepage and clearance, optimized for reinforced isolation in high-voltage systems.

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 |
|---|---|---|---|
| ADUM140D1BRIZ | Narrow-body SOIC_N (R-16) package; 3.0 kVRMS isolation rating; same pinout and electrical specs | Lower creepage/clearance (4.0 mm vs. 7.8 mm); unsuitable for 400 V+ working voltage designs requiring reinforced insulation | Select ADUM140D1BRIZ only when board space is constrained and system voltage <300 V RMS. |
| SI8641ED-B-IS | Silicon Labs capacitive isolator; 5 kVRMS rating; 150 Mbps; different pinout (no DISABLE1 input) | Lacks dedicated disable input and fail-safe high option; requires external logic for safe power-loss behavior | Choose SI8641ED-B-IS when higher isolation voltage is needed and disable functionality is implemented externally. |
Compared with ADUM140D1BRWZ, ADUM140D1BRIZ offers identical performance in a smaller footprint but reduced isolation margin, while SI8641ED-B-IS provides higher voltage rating but omits integrated disable and fail-safe logic-requiring additional components for functional safety compliance.

FAQ
What is the isolation voltage rating of the ADUM140D1BRWZ?
The ADUM140D1BRWZ has a rated dielectric insulation voltage of 3.75 kVRMS for 1 minute, validated per UL 1577 and DIN EN IEC 60747-17 (VDE 0884-17). This applies to the RW-16 wide-body SOIC package and supports reinforced insulation in industrial and medical applications up to 400 V working voltage.
Does the ADUM140D1BRWZ support level translation between different supply voltages?
Yes, the ADUM140D1BRWZ supports independent 1.8 V to 5 V supplies on each side (VDD1 and VDD2), enabling true bidirectional level translation. For example, it can interface a 1.8 V FPGA I/O bank with a 5 V isolated ADC, maintaining full timing specifications across the voltage range.
What fail-safe behavior does the ADUM140D1BRWZ provide?
The ADUM140D1BRWZ is configured as a high-fail device: when VDD1 is unpowered or DISABLE1 is asserted, all outputs (VOA–VOD) transition to and hold a logic-high state. This behavior is hardware-defined and requires no external circuitry, supporting IEC 61508 and ISO 26262 safety goals.
Is the ADUM140D1BRWZ pin-compatible with earlier ADuM140x series devices?
ADUM140D1BRWZ is pin-compatible with ADUM140D0BRWZ and ADUM140E1BRWZ within the same RW-16 package, sharing identical pinout, supply connections, and enable/disable logic. However, it is not compatible with narrow-body (R-16) or QSOP (RQ-16) variants due to differing package footprints and creepage requirements.
What safety certifications does the ADUM140D1BRWZ hold?
The ADUM140D1BRWZ is certified to UL 1577 (3000 V rms), IEC/EN/CSA 60950-1, IEC/CSA 60601-1 (medical), IEC/CSA 61010-1 (test equipment), and CQC GB 4943.1. It also meets DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation lifetime and material group II tracking resistance.
