概述

Description

ADuM3223CRZ-RL7 is a 3-channel digital isolator from Analog Devices (iCoupler family). It provides galvanic isolation between the input side (VDD1) and output side (VDD2) for three independent, unidirectional digital signals. It supports independent 2.7–5.5 V supplies on both sides, enabling safe interfacing between a microcontroller and higher-voltage circuitry. Key benefits include low propagation delay, good common-mode transient immunity, and robust isolation (VIORM typically around a few kV rms, suitable for many safety standards). The CRZ suffix designates a RoHS-compliant LFCSP package, and RL7 indicates reel packaging for automated assembly. Common uses: isolating SPI/UART/I2C lines, protecting microcontrollers, motor drivers, and power-supply control in noisy or high-voltage environments.

Features

ADuM3223CRZ-RL7 is an iCoupler-based, 3-channel digital isolator for SPI/isolation needs. Key features:
- 3 isolated channels for SPI-style signaling (suitable for isoSPI/SPI bridge)
- Up to about 25 Mbps per channel data rate
- Reinforced isolation between sides (typical 5 kV RMS)
- Dual-supply operation: VDD1 and VDD2 (3.3 V or 5 V, within spec)
- Wide operating temperature: -40°C to +125°C
- 8-pin SOIC (RZ) package; RoHS compliant; reel packaging RL7
- Low power consumption with fast propagation and low skew
- High common-mode transient immunity
- Integrated fail-safe/ default-state behavior for robust SPI interfaces
Note: precise electricals (exact VIH/VIL, propagation delay, and isolation rating in your variant) should be verified in the official datasheet for ADuM3223CRZ-RL7.

Package

It’s a 16‑lead Small Outline IC package (SOIC-16), CRZ code, RoHS compliant, on a 7-inch reel (RL7).

Pinout

- Pin count: 16 pins (16‑lead package).
- Function: 3‑channel digital isolator (iCoupler). Provides three isolated data channels between the two sides, with separate supplies: VDD1/VSS1 on the primary side and VDD2/VSS2 on the secondary side (isolation barrier between the sides).

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
About the company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits (ICs), sensors, and related products.

Application

ADuM3223CRZ-RL7 is a 3-channel digital isolator for galvanically isolating low-voltage control logic from high-voltage/noisy domains. Applications include:
- Industrial automation and control
- Motor drives and power electronics
- Data acquisition and instrumentation
- Isolated communication interfaces (SPI/I2C/UART; RS-485/RS-232)
- Medical equipment (patient-safety isolation)
- Automotive and battery-management systems

Equivalent

There isn’t an exact one-to-one cross for ADUM3223CRZ‑RL7. Closest options are other 3-channel digital isolators, such as TI’s ISO7220/ISO7221 family (depends on required Vdd levels) and similar 3‑channel devices from other vendors. For an exact replacement, provide required Vdd1/Vdd2, isolation rating, package, and channel configuration and I’ll provide precise cross-references.
