Product details
Overview
ADUM3200CRZ-RL7 from Analog Devices is a dual-channel, bidirectional digital isolator based on iCoupler® transformer technology, providing galvanic isolation between two independent signal paths. It supports data rates up to 25 Mbps (NRZ), operates at 3.3 V or 5 V on either side, and delivers precise timing with ≤3 ns pulse width distortion and ≤3 ns channel-to-channel matching - enabling robust SPI and RS-485 interface isolation in industrial motor drives and battery monitoring systems.
For engineers reviewing the ADUM3200CRZ-RL7 datasheet, ADUM3200CRZ-RL7 pinout, ADUM3200CRZ-RL7 application, or ADUM3200CRZ-RL7 equivalent, key selection criteria include its enhanced system-level ESD reliability per IEC 61000-4-x, 2500 VRMS isolation rating, 125°C automotive-grade operation, and mixed-voltage level translation capability across the isolation barrier.
Technical Context
The ADUM3200CRZ-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 deterministic propagation delay (≤45 ns max at 125°C) and maintains signal integrity under high common-mode transients (>25 kV/µs).
It features dual-supply operation (VDD1/VDD2 = 3.3 V or 5 V, independently configurable), enabling voltage translation between domains, and integrates refresh circuitry to ensure DC correctness without external components. The device meets DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation with VIORM = 560 VPEAK and UL 1577 certification at 2500 VRMS for 1 minute.
Key Specifications

FAQ
What is the maximum data rate supported by ADUM3200CRZ-RL7?
ADUM3200CRZ-RL7 supports a maximum data rate of 25 Mbps in NRZ format. This is verified across all operating conditions including 125°C ambient temperature and mixed 3.3 V/5 V supply configurations. The device maintains signal integrity up to this rate without requiring encoding or pre-emphasis, making it suitable for high-speed SPI clocking and real-time serial communication in industrial and automotive systems.
Does ADUM3200CRZ-RL7 support bidirectional communication on each channel?
Yes, ADUM3200CRZ-RL7 supports true bidirectional communication on both Channel 1 (Pins 3 and 7) and Channel 2 (Pins 4 and 8). Each channel operates independently with automatic direction detection and DC-correct refresh circuitry, eliminating the need for external direction-control signals or additional logic - simplifying PCB layout and firmware design for protocols like UART and half-duplex SPI.
What safety certifications does ADUM3200CRZ-RL7 hold?
ADUM3200CRZ-RL7 is certified to UL 1577 (2500 VRMS for 1 minute), 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 confirm its suitability for reinforced insulation in industrial equipment and automotive applications meeting AEC-Q100 Grade 1 thermal requirements.
Can ADUM3200CRZ-RL7 operate with different supply voltages on each side?
Yes, ADUM3200CRZ-RL7 supports independent 3.3 V or 5 V supplies on VDD1 and VDD2 - enabling seamless level translation between domains. For example, it can isolate a 3.3 V microcontroller from a 5 V RS-485 transceiver without external level shifters, preserving signal timing and reducing BOM count in mixed-voltage systems.
How does ADUM3200CRZ-RL7 differ from standard optocouplers in terms of reliability?
ADUM3200CRZ-RL7 uses iCoupler® monolithic transformer technology instead of LEDs and photodiodes, eliminating optocoupler failure modes such as CTR degradation, nonlinear transfer functions, and temperature-dependent aging. Its MTTF exceeds 25 years at 125°C, and it guarantees consistent propagation delay, pulse width distortion (<3 ns), and channel matching - critical for timing-sensitive applications like motor control and battery monitoring.
