Analog Devices Inc. ADUM241D0BRIZ

Overview

ADUM241D0BRIZ from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation, delivering 5.0 kV_rms withstand voltage, 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 is qualified for automotive applications in a 16-lead SOIC_W package.

For engineers reviewing the ADUM241D0BRIZ datasheet, ADUM241D0BRIZ pinout, ADUM241D0BRIZ application, or ADUM241D0BRIZ equivalent, this page provides verified specifications, fail-safe output behavior, safety certifications (UL, VDE, IEC 60601-1), and real-world use cases in SPI isolation and industrial field bus systems.

Technical Context

The ADUM241D0BRIZ implements four independent unidirectional channels with input-side power (VDD1) and output-side power (VDD2) operating independently from 1.8 V to 5 V. Its iCoupler® technology ensures dc-correct output states without input transitions and supports fail-safe high/low output options during input power loss.

It features tight channel matching (≤3.0 ns), low pulse width distortion (≤3 ns), and high common-mode transient immunity (100 kV/µs). Safety compliance includes reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 849 V_peak and UL 1577 certification at 5000 V_rms.

FAQ

What is the maximum guaranteed data rate for ADUM241D0BRIZ?

The ADUM241D0BRIZ 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), as confirmed in Table 1 through Table 7 of the Rev. E datasheet. This rate is validated under worst-case conditions including CL = 15 pF loading and full temperature range, making ADUM241D0BRIZ suitable for high-speed SPI, RS-485, and digital encoder interfaces.

Does ADUM241D0BRIZ support level translation between different supply voltages?

Yes, ADUM241D0BRIZ supports true bidirectional level translation: VDD1 (input side) and VDD2 (output side) can each operate independently from 1.8 V to 5 V. This allows direct interfacing-for example-between a 1.8 V FPGA I/O bank and a 3.3 V ADC, with no external level-shifting components required. The input thresholds scale as 0.7×VDDx and 0.3×VDDx, ensuring robust noise margins across voltage combinations.

What safety certifications does ADUM241D0BRIZ hold?

ADUM241D0BRIZ holds UL 1577 (5000 V_rms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation (VIORM = 849 V_peak), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1 approvals. These are documented in Tables 12 and 13 of the datasheet and apply specifically to the RW-16 SOIC_W package variant of ADUM241D0BRIZ.

How does the fail-safe output function work on ADUM241D0BRIZ?

ADUM241D0BRIZ offers user-selectable fail-safe output states (high or low) activated when the input-side supply (VDD1) is absent or the DISABLE1 pin is asserted. This behavior is implemented via internal circuitry that overrides output drivers to a predefined logic state-ensuring deterministic system behavior during power sequencing or fault conditions. The specific fail-safe polarity is fixed per part number; ADUM241D0BRIZ is configured for fail-safe low.

Is ADUM241D0BRIZ pin-compatible with earlier ADuM240x or ADuM241x series devices?

No, ADUM241D0BRIZ is not pin-compatible with ADuM2400/ADuM2401/ADuM2402 or ADuM241E1 variants. While ADuM241E1/ADuM242E1 are explicitly stated as pin-compatible with ADuM2400-series, the D0 suffix (e.g., ADUM241D0BRIZ) denotes a distinct pinout and functional configuration-including dedicated DISABLE1 and VE2 control pins not present in legacy parts. Always verify against the Pin Configurations section (page 17) of the Rev. E datasheet.
