概述

Description

ADuM1401WSRWZ is Analog Devices’ four‑channel digital isolator (iCoupler technology). It provides galvanic isolation between two power domains (VDD1 and VDD2) for four independent digital channels, enabling safe data transfer across an isolation barrier without optocouplers.
Key points:
- Four isolated channels with bidirectional or unidirectional use per channel, using separate supply pins on each side.
- High isolation voltage rating (typical for iCoupler devices) and good noise immunity, with low propagation delay and low power.
- Eliminates ground loops and protects microcontrollers or digital logic from high-voltage/noise environments.
- RoHS-compliant packaging option denoted by the suffix WSRWZ; the exact package type (e.g., 8‑lead small‑outline) is specified in the datasheet.
For precise electrical specs, timing, and the exact package details, consult the ADuM1401 datasheet and the packaging documentation for the WSRWZ variant.

Features

ADuM1401WSRWZ is an 8-pin, iCoupler-based digital isolator. Key features:
- 4 isolated channels (galvanic isolation between input and output)
- Dual-supply operation (VDD1 on the input side and VDD2 on the output side)
- High isolation voltage (UL1577-rated, typically 5 kV RMS per channel)
- Bidirectional/unidirectional data paths (depending on channel configuration)
- High-speed data transfer with tens of Mbps range (suitable for fast logic signaling)
- Low propagation delay and robust common-mode transient immunity
- Compatible with 3.3V/5V logic on both sides
- Wide operating temperature range (typically -40°C to +125°C)
- Small 8-pin package (WSRWZ variant is RoHS/lead-free, tape-and-reel packaging)
Note: exact data rates and pin directions vary by channel configuration; consult the datasheet for precise specs.

Package

The ADUM1401WSRWZ uses a 16-lead wide-body surface-mount SOIC (SOIC-16) package, RoHS-compliant, with Tape & Reel packaging.

Pinout

- Pin count: 16 pins (16-pin package).
- Function: ADUM1401WSRWZ is a 4-channel digital isolator (iCoupler) that provides four isolated digital signal paths across a galvanic barrier, using two isolated power rails (VDD1/VSS1 and VDD2/VSS2).

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
ADI is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits (including isolation products and data converters) for a wide range of applications.

Application

ADuM1401WSRWZ is a quad-channel digital isolator (iCoupler) enabling galvanic isolation of four digital lines between two systems. Typical applications:
- Isolated I/O for industrial automation (sensors, PLCs)
- Isolated SPI/I2C/UART interfaces between microcontrollers
- Automotive, medical, and other safety-critical electronics
- Power-supply and motor-drive control signals requiring isolation
- EMI reduction and ground-loop prevention in mixed-signal systems

Equivalent

Equivalent products (4-channel digital isolators with similar specs) include:
- TI ISO784x family (ISO7840/7841/7842)
- Silicon Labs Si86x family (e.g., Si8620/Si8624)
- Broadcom/Avago HCPL-7840/7841 series
- Analog Devices ADuM1250/ADuM1251 (4-channel SPI isolators)
These provide similar isolation (typically 5 kV) and quad-channel digital isolation suitable as substitutes. Always verify pinout, voltage, and speed specs for your design.
