Product details
Overview
ADUM3200BRZ-RL7 from Analog Devices is a dual-channel, bidirectional digital isolator based on iCoupler® transformer technology, delivering 25 Mbps data rate, 3 ns pulse width distortion, and 25 kV/µs common-mode transient immunity. It operates at 3.3 V or 5 V on either side, enabling level translation across the isolation barrier, and is qualified for automotive applications up to 125°C in narrow-body SOIC-8 packaging.
For engineers reviewing the ADUM3200BRZ-RL7 datasheet, ADUM3200BRZ-RL7 pinout, ADUM3200BRZ-RL7 application, or ADUM3200BRZ-RL7 equivalent, key selection criteria include system-level ESD robustness per IEC 61000-4-x, precise channel-to-channel timing matching (≤3 ns), and mixed-supply operation (3.3 V/5 V) without external level shifters.
Technical Context
The ADUM3200BRZ-RL7 implements two independent unidirectional or bidirectional isolation channels using monolithic air-core transformers, eliminating LED-photodiode aging and CTR drift inherent in optocouplers. Its architecture supports dc-to-25 Mbps NRZ signaling with guaranteed timing performance across −40°C to +125°C.
It features enhanced system-level ESD reliability via layout and circuit modifications relative to earlier iCoupler generations, validated under IEC 61000-4-2/4-4/4-5. Insulation meets UL 1577 (2500 VRMS/1 min), DIN EN IEC 60747-17 (VIORM = 560 VPEAK), and IEC/EN/CSA 62368-1.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8620ED-B-IS | Capacitive isolation; 25 Mbps; 3.75 kVRMS rating; no automotive qualification; higher CMTI (50 kV/µs). | Preferred for non-automotive industrial systems requiring highest CMTI; lacks IEC 61000-4-x system-level ESD enhancements. | Select SI8620ED-B-IS when CMTI >35 kV/µs is mandatory and automotive qualification is unnecessary. |
| ISO7721DR | Capacitive isolation; 100 Mbps; 5000 VRMS; 125°C operation; lower quiescent current (1.5 mA/ch @ 0 Mbps); no system-level ESD certification. | Better suited for high-speed, low-power applications like server PMBus or PCIe auxiliary links; not tested to IEC 61000-4-x system-level ESD. | Choose ISO7721DR for bandwidth-critical designs where 100 Mbps is needed and system-level ESD robustness is managed at board level. |
Compared with SI8620ED-B-IS and ISO7721DR, the ADUM3200BRZ-RL7 uniquely combines automotive qualification, system-level IEC 61000-4-x ESD hardening, and precise 3 ns timing matching-making it optimal for safety-relevant battery monitoring and motor control where board-level ESD margin is constrained.

FAQ
What is the maximum data rate supported by the ADUM3200BRZ-RL7?
The ADUM3200BRZ-RL7 supports a maximum data rate of 25 Mbps in NRZ format across its dual isolation channels. This is verified over the full operating temperature range (−40°C to +125°C) and under both 3.3 V and 5 V supply conditions, with timing parameters including pulse width distortion ≤3 ns maintained at this rate.
Does the ADUM3200BRZ-RL7 support level translation between 3.3 V and 5 V domains?
Yes, the ADUM3200BRZ-RL7 supports true bidirectional level translation: VDD1 may be 3.3 V while VDD2 is 5 V (or vice versa), with logic thresholds scaling to 0.3× and 0.7× respective supply voltages. This eliminates external level shifters in mixed-voltage systems such as 3.3 V MCUs driving 5 V RS-485 transceivers.
Is the ADUM3200BRZ-RL7 qualified for automotive applications?
Yes, the ADUM3200BRZ-RL7 is explicitly qualified for automotive applications per AEC-Q100 and rated for continuous operation at 125°C ambient. It carries automotive-grade part numbers (e.g., ADUM3200W), meets IEC/EN/CSA 62368-1, and includes enhanced system-level ESD robustness per IEC 61000-4-x - all confirmed in the Rev. G datasheet.
What safety certifications does the ADUM3200BRZ-RL7 hold?
The ADUM3200BRZ-RL7 is certified to UL 1577 (2500 VRMS/1 min), DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 560 VPEAK, IEC/EN/CSA 62368-1, IEC/CSA 61010-1, and CQC GB4943.1. These approvals validate its suitability for reinforced insulation in safety-critical end equipment.
How does the ADUM3200BRZ-RL7 differ from standard optocouplers in terms of power consumption?
The ADUM3200BRZ-RL7 consumes significantly less power than comparable optocouplers: at 25 Mbps, it draws ≤7.0 mA per channel at 5 V (vs. typical optocoupler currents >10 mA at much lower speeds). Its iCoupler® transformer architecture eliminates LED bias current and driver losses, achieving ~1/6 the power of optocouplers at equivalent data rates.
