Analog Devices Inc. ADUM2200BRWZ

Overview

ADUM2200BRWZ from Analog Devices is a dual-channel digital isolator based on iCoupler® transformer technology, providing 5 kV rms isolation, 10 Mbps data rate, and precise timing (≤3 ns pulse width distortion). It operates across 3.0–5.5 V supplies on both sides, supports 3.3 V/5 V level translation, and is qualified for industrial and medical applications requiring reinforced insulation.

For engineers reviewing the ADUM2200BRWZ datasheet, ADUM2200BRWZ pinout, ADUM2200BRWZ application, or ADUM2200BRWZ equivalent, this page delivers verified specifications, SOIC-16 wide-body package details, safety certifications (UL 1577, VDE 0884-17), and real-world use cases in RS-485 transceiver isolation, battery monitoring, and motor drive gate driver interfaces.

Technical Context

The ADUM2200BRWZ implements two independent unidirectional isolation channels using monolithic air-core transformers, eliminating LED/photodiode dependencies. Its patented refresh circuit ensures DC correctness during power-up and signal inactivity, while internal CMOS logic enables direct interfacing with microcontrollers and FPGAs without external drivers.

It features high common-mode transient immunity (>25 kV/µs), channel-to-channel matching ≤3 ns, and operates across −40°C to +105°C (B grade). The device supports mixed-voltage operation (e.g., 5 V side 1 / 3.3 V side 2), enabling seamless voltage domain bridging in isolated power supply control and sensor interface circuits.

Key Specifications

Pinout & Package

ADUM2200BRWZ uses a 16-lead SOIC wide-body package (RW-16) with 7.8 mm creepage and clearance, optimized for reinforced insulation in industrial and medical designs. Pin 1 and Pin 7 are internally connected GND1; Pin 9 and Pin 16 are internally connected GND2. No-connection (NC) pins are electrically isolated and must not be soldered to traces.

FAQ

What is the maximum continuous working voltage supported by ADUM2200BRWZ?

ADUM2200BRWZ supports a maximum continuous working voltage of 645 V peak under reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17), validated for bipolar waveforms. This rating applies to the RW-16 package and is confirmed by 100% production partial discharge testing at 1209 V peak. The device also meets 456 V rms VIOWM for AC applications per IEC 62368-1.

Does ADUM2200BRWZ support bidirectional communication?

No, ADUM2200BRWZ provides two unidirectional channels (VIA→VOA and VIB→VOB). For bidirectional isolation, ADUM2201BRWZ is the functional complement - it swaps one input/output pair (VIA↔VOA) to enable half-duplex UART or I²C isolation. The ADUM2200BRWZ pinout and internal architecture are fixed for input-on-side-1, output-on-side-2 operation.

Can ADUM2200BRWZ operate with different supply voltages on each side?

Yes, ADUM2200BRWZ supports mixed-supply operation: side 1 (VDD1) and side 2 (VDD2) may be independently set between 3.0 V and 5.5 V. Verified configurations include 5 V / 3.3 V and 3.3 V / 5 V, enabling level translation without external level shifters. Electrical characteristics (e.g., propagation delay, current draw) are specified per configuration in Tables 7–11 of the datasheet.

What safety certifications does ADUM2200BRWZ hold?

ADUM2200BRWZ holds UL 1577 (5000 V rms, 1 min), CSA/IEC 62368-1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, CQC GB4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 V peak. Certification applies to the RW-16 package variant; the RI-16-2 variant adds enhanced creepage for higher pollution degree environments.

How does the refresh feature in ADUM2200BRWZ work?

The ADUM2200BRWZ incorporates a patented internal refresh circuit that periodically samples input states and retransmits them across the isolation barrier during static conditions. This ensures output logic levels remain valid even with zero input transitions - critical during power-up, brownout, or idle bus states. No external clock or control signal is required; the refresh operates autonomously at ~1.2 Mbps equivalent rate.
