Product details

Overview

ADuM340E0BRWZ from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation, delivering 5.7 kV_rms reinforced isolation, 150 Mbps data rate at 5 V, 6.2 ns typical propagation delay, and ±8 kV IEC 61000-4-2 ESD protection across the barrier-used in SPI isolation for industrial PLCs and motor drives.

For engineers reviewing the ADuM340E0BRWZ datasheet, ADuM340E0BRWZ pinout, ADuM340E0BRWZ application, or ADuM340E0BRWZ equivalent, this page provides verified specifications, SOIC-16 package mapping, fail-safe E0 (output low on input-side power loss), safety certifications (UL 1577, VDE 0884-17), and real-world design context for high-noise industrial signal isolation.

Technical Context

The ADuM340E0BRWZ implements four independent unidirectional CMOS-isolated channels using monolithic air-core transformers, with separate VDD1/VDD2 supplies enabling 2.25 V to 5.5 V level translation across the barrier. Its timing architecture achieves ≤10 ns max propagation delay and ≤3 ns channel matching at 5 V operation.

It features dual enable inputs (VE1/VE2) supporting tristate output control, undervoltage lockout (2.2 V threshold), and robust noise immunity: 180 kV/µs common-mode transient immunity and compliance with CISPR 32 Class B emissions at 5 Mbps.

Key Specifications

Parameter	Value and Actual Design Meaning
Isolation Rating	5.7 kV_rms for 1 minute (SOIC-16 RW-16 package); enables reinforced isolation in industrial mains-connected systems
Data Rate	150 Mbps maximum (5 V operation); supports high-speed SPI, CAN FD, and PWM feedback loops
Propagation Delay	6.2 ns typical, ≤10 ns max (5 V); ensures tight timing control in closed-loop motor control
Supply Range	2.25 V to 5.5 V per side; allows interoperability between 3.3 V microcontrollers and 5 V fieldbus peripherals
Fail-Safe Output	E0 variant: outputs default low when input-side VDD1 is absent; critical for safe shutdown in power converter gate drivers
ESD Protection	±8 kV contact discharge across isolation barrier (IEC 61000-4-2); prevents latch-up during board handling and field surges
Operating Temperature	−40°C to +125°C ambient; qualified for under-hood automotive and industrial drive environments

Pinout & Package

ADuM340E0BRWZ is housed in a 16-lead, RoHS-compliant wide-body SOIC package (RW-16), with creepage/clearance ≥8.3 mm and VIORM = 1173 V_peak. Pin functions are validated per Analog Devices' datasheet Figure 19 (Pin Configurations) and Table 12.

Pin/Terminal	Circuit Role	Design Meaning
VDD1	Input-side supply	Power source for channels A–D inputs and internal logic; must be stable before enabling signals
GND1	Input-side ground	Reference for all input signals and VE1/VE2 enable pins; requires low-inductance connection to minimize noise coupling
VA, VB, VC, VD	Input data channels	CMOS-compatible inputs accepting 2.25–5.5 V logic; hysteresis of 0.85 V improves noise margin
VE1, VE2	Output-enable controls	Active-low enables for two channel groups; pulling either low places corresponding outputs in high-Z state
VDD2	Output-side supply	Independent supply for isolated outputs; supports level translation up to 5.5 V
GND2	Output-side ground	Isolated reference for outputs; must be separated from GND1 by ≥8.3 mm PCB spacing
OA, OB, OC, OD	Isolated output channels	CMOS outputs with VOH ≥ VDD2 − 0.4 V (at 4 mA), VOL ≤ 0.4 V; E0 variant defaults low on VDD1 loss

Key Features

Feature	Design Value
High CMTI	180 kV/µs typical; maintains signal integrity in high-dV/dt environments like IGBT gate drivers and VFDs
Low Power at Speed	<1.65 mA/channel at 1 Mbps (5 V); enables energy-efficient isolation in battery-backed or thermally constrained modules
Backward Compatibility	Pin- and function-compatible with ADuM140E/ADuM240E families; simplifies upgrade paths without PCB redesign
AEC-Q100 Qualified	Grade 1 (−40°C to +125°C); validated for automotive powertrain and charging systems requiring long-term reliability
Regulatory Approvals	DIN EN IEC 60747-17 (VDE 0884-17), UL 1577, IEC/EN/CSA 62368-1, IEC/CSA 60601-1; reduces system-level certification effort

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
ADUM340E1BRWZ	E1 variant: outputs default high on VDD1 loss vs. E0's default low; identical timing, isolation, and package	Required where fail-safe logic demands active-high assertion (e.g., enable-to-run systems)	Select ADUM340E1BRWZ only if system safety analysis mandates high-default behavior on input power loss.
SI8640ED-B-IS	Capacitive isolation; 5 kV_rms, 150 Mbps, but lower CMTI (75 kV/µs) and no AEC-Q100 qualification	Suitable for non-automotive industrial use where cost sensitivity outweighs extreme noise immunity needs	Choose SI8640ED-B-IS only for cost-driven designs where 180 kV/µs CMTI and automotive qualification are not required.

Compared with ADUM340E0BRWZ, the ADUM340E1BRWZ offers identical performance except fail-safe polarity, while SI8640ED-B-IS trades CMTI and qualification for lower unit cost-making ADUM340E0BRWZ optimal for high-reliability, noise-intensive, or automotive-qualified applications.

FAQ

What is the isolation voltage rating of the ADuM340E0BRWZ?

The ADuM340E0BRWZ provides 5.7 kV_rms isolation for 1 minute in its SOIC-16 RW-16 package, with a peak working voltage (VIORM) of 1173 V_peak. This rating is certified per DIN EN IEC 60747-17 (VDE 0884-17) and UL 1577, making it suitable for reinforced insulation in industrial mains-connected equipment. The ADuM340E0BRWZ meets IEC/EN/CSA 62368-1 and IEC/CSA 60601-1 safety standards.

Does the ADuM340E0BRWZ support level translation between different supply voltages?

Yes, the ADuM340E0BRWZ supports bidirectional level translation between 2.25 V and 5.5 V on each side-VDD1 and VDD2 can operate independently within that range. For example, it can isolate a 3.3 V SPI master from a 5 V isolated ADC, with input thresholds scaling to 0.7×VDDx and 0.3×VDDx. This eliminates external level shifters in mixed-voltage systems.

What does "E0" signify in ADuM340E0BRWZ?

The "E0" suffix in ADuM340E0BRWZ denotes the fail-safe output configuration: when the input-side supply (VDD1) is absent or drops below UVLO threshold, all four outputs (OA–OD) transition to and hold a logic low state. This behavior is critical for safety-critical applications such as gate driver enable signals, where loss of control power must force a safe shutdown condition.

Is the ADuM340E0BRWZ pin-compatible with earlier ADuM140E devices?

Yes, the ADuM340E0BRWZ is pin- and function-compatible with ADuM140E/ADuM240E families in the same SOIC-16 RW-16 package. It retains identical pinout, supply sequencing, and enable logic (VE1/VE2), allowing drop-in replacement without PCB changes-while delivering improved 150 Mbps data rate, lower propagation delay (6.2 ns typ), and enhanced CMTI (180 kV/µs).

What safety certifications apply to the ADuM340E0BRWZ?

The ADuM340E0BRWZ holds UL 1577 (5700 V_rms/1 min), DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 1173 V_peak, IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (medical), and IEC/CSA 61010-1 (test equipment). It also carries CQC GB4943.1 and AEC-Q100 Grade 1 qualification, confirming suitability for automotive, medical, and industrial safety-critical systems.
