概述

Description

ADuM3190SRQZ is an Analog Devices iCoupler digital isolator. It provides four independent, galvanically isolated logic channels, allowing signals to cross an isolation barrier between two logic domains. It’s typically used to implement isolated SPI/UART/I2C interfaces and other digital links in safety-critical or noisy environments. The SRQZ suffix indicates a RoHS-compliant, surface-mount 16‑lead package variant. For exact electrical specs (isolation rating, propagation delay, supply pins VDD1/VDD2, current, timing, and the recommended PCB layout), consult the ADuM3190 datasheet on Analog Devices’ website.

Features

ADuM3190SRQZ features (highlights):
- iCoupler digital isolator with four isolated channels for SPI-style interfaces
- Separate supply rails on each side: VDD1 and VDD2, no galvanic ground return required
- Isolation rating up to 5 kV RMS between sides (safety/robustness)
- Automotive-grade, extended temperature range (-40°C to +125°C) with SRQZ package
- Bidirectional/slightly bidirectional data paths designed for SPI (MOSI, MISO, SCK, CS)
- TTL/CMOS-compatible inputs and outputs
- Wide supply range on both sides (typically 3.0–5.5 V)
- High noise immunity (common-mode transient immunity) suitable for harsh environments
- Low propagation delay and matched channel skew for timing-critical interfaces
- 8-pin package (SOIC) with RoHS-compliant packaging
Note: For exact electrical specs (propagation delay, channel skew, CMTI, maximum data rate), please refer to the ADuM3190SRQZ datasheet.

Package

The ADUM3190SRQZ is supplied in a 16‑lead SOIC surface‑mount package (SOIC‑16), shipped on tape and reel (SRQZ denotes the SOIC package with reel packaging).

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
What kind of company: ADI is a multinational semiconductor company that designs and manufactures analog, mixed-signal and digital signal‑processing integrated circuits and modules—covering amplifiers, data converters, power management and isolation products (such as the ADuM digital isolator family)—serving industrial, automotive, communications and consumer markets.

Application

ADuM3190SRQZ is a 3-channel digital isolator used to galvanically isolate digital signals between low-voltage control logic and higher-voltage/noisy domains. Common applications: isolated SPI/I2C/UART interfaces; isolated sensors/actuators in industrial automation and motor control; isolated data acquisition and instrumentation; automotive/EV electronics; medical equipment; power-management and isolated monitoring systems.

Equivalent

Equivalent parts are other high-speed digital galvanic isolators with matching channel count, data rate and isolation: TI ISO7x/ISO3x families (ISO77xx, ISO35xx), Silicon Labs Si86xx series, Broadcom/Avago ACPL (ACPL-77xx) devices, NVE IL7xx series, and Murata VISO isolators. Pick the exact model by matching supply voltage, channels, data rate and isolation rating.
