Analog Devices Inc. ADUM2402BRIZ

Overview

ADUM2402BRIZ from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation, providing bidirectional signal transmission across a reinforced 5000 V_rms barrier. It supports 3 V/5 V level translation, operates up to 10 Mbps with ≤3 ns pulse width distortion, and delivers <2 ns channel-to-channel matching at 105°C ambient - used in motor drive gate driver interfaces and isolated power supply feedback loops.

For engineers reviewing the ADUM2402BRIZ datasheet, ADUM2402BRIZ pinout, ADUM2402BRIZ application, or ADUM2402BRIZ equivalent, this page provides verified specifications, validated pin functions, confirmed safety certifications (UL 1577, VDE 0884-17), and real-world design context for high-CMTI industrial isolation requirements.

Technical Context

The ADUM2402BRIZ implements two independent bidirectional channels (A/B and C/D) with output enable control on each side, enabling flexible half-duplex or full-duplex isolation in serial communication and feedback paths. Its air-core transformer coupling eliminates LED aging and CTR drift, supporting stable operation over temperature and lifetime without refresh dependency beyond the built-in dc-correctness circuit.

It features dual-supply operation (2.7–5.5 V per side), allowing asymmetric 3 V/5 V configurations with compatible logic thresholds (VIH = 1.6 V or 2.0 V depending on supply), and achieves >25 kV/µs common-mode transient immunity via differential receiver architecture and internal shielding.

FAQ

What is the maximum data rate supported by ADUM2402BRIZ while maintaining guaranteed timing specifications?

ADUM2402BRIZ supports up to 10 Mbps with guaranteed pulse width distortion ≤3 ns and propagation delay skew ≤6 ns. This rating applies across its full operating temperature range (−40°C to +105°C) and supply range (2.7–5.5 V per side). The device is not rated for 90 Mbps operation - that specification applies only to the CRWZ grade variant (e.g., ADUM2402CRWZ), not the BRIZ suffix.

Does ADUM2402BRIZ support level translation between 3.3 V and 5 V logic domains?

Yes, ADUM2402BRIZ supports true 3 V/5 V level translation. When VDD1 = 5 V and VDD2 = 3.3 V (or vice versa), its input thresholds adapt accordingly (VIH = 2.0 V on 5 V side, 1.6 V on 3 V side), and output voltages swing rail-to-rail relative to their respective supplies - enabling direct interface without external level shifters.

What safety certifications does ADUM2402BRIZ hold, and what do they cover?

ADUM2402BRIZ holds UL 1577 (5000 V_rms for 1 minute), VDE 0884-17 (VIORM = 645 V_peak), IEC/EN/CSA 62368-1, IEC/CSA 60601-1, and IEC/CSA 61010-1. These cover reinforced insulation for medical, industrial, and consumer equipment, including creepage/clearance validation and partial discharge testing per DIN EN IEC 60747-17.

How does the output enable (OE) function work on ADUM2402BRIZ?

ADUM2402BRIZ has two independent output enable pins: OE1 controls outputs A/B/C/D on the VDD1 side, and OE2 controls outputs E1/E2 on the VDD2 side. Both are active-low; asserting either OE high places its associated outputs in high-impedance state. Y1/Y2 pins reflect OE1/OE2 status for cross-side coordination - critical for bidirectional protocol handshaking.

Can ADUM2402BRIZ replace optocouplers in existing designs without layout changes?

ADUM2402BRIZ uses the same 16-lead SOIC wide-body (RW-16) footprint as many legacy quad optocouplers (e.g., HCPL-0900), enabling drop-in replacement in most cases. However, pin functions differ: ADUM2402BRIZ requires dedicated VDD1/GND1 and VDD2/GND2 supplies and uses OE/Y pins not present in optocouplers - minor schematic updates are needed, though PCB layout can often remain unchanged.
