Overview

Description

ADuM1400ARW is Analog Devices’ 4-channel digital isolator (iCoupler) used to galvanically isolate SPI-like signals between two domains. It provides four unidirectional channels with separate VDD1 and VDD2 rails, so you can wire it to implement isoSPI: typically two master-to-slave lines (e.g., SCK and MOSI), one slave-to-master line (MISO), and a chip-select or similar line. No optocouplers are needed, offering fast edge rates, reduced power, and protection against ground loops and voltage spikes. The ARW suffix denotes the package/kit option (an 8-pin device with tape-and-reel availability). Common applications include isolating microcontrollers from sensors, ADCs/DACs, motor controllers, and other peripherals in industrial, automotive, or safety-critical systems.

Features

ADuM1400ARW is a 4-channel digital isolator (iCoupler technology) from Analog Devices. Key features:
- Four independent, unidirectional digital isolation channels
- galvanic isolation between input and output domains (no optocouplers)
- Dual supplies: VDD1 and VDD2 allow compatible logic levels on both sides (e.g., 3.3V/5V)
- Isolation rating: typically reinforced isolation (up to a few kV rms per device)
- High-speed data transfer: tens of Mbps range per channel with low propagation delay and low channel-to-channel skew
- Low power consumption
- ESD protection on I/O
- Wide operating temperature options (industrial-grade variants available)
- Practical for isolating SPI, I2C, UART, and other digital interfaces
- Package: ARW (16-pin) standard MSOP/SOIC form factor
Note: exact isolation voltage, speed, and thermal specs vary by variant; refer to the ADuM1400ARW datasheet for precise numbers.

Package

ADuM1400ARW is in a 16‑lead surface‑mount package (16‑pin SOIC), RoHS compliant. The ARW code is the ADI package variant for this device.

Pinout

- Pin count: 16 pins (16‑pin package, ROHS indicated by ARW).
- Function: Four‑channel unidirectional digital isolator (iCoupler). Provides galvanic isolation between input side (DI1–DI4, VDD1/GND1) and output side (DO1–DO4, VDD2/GND2).

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI)
- What kind of company: A US-based multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits, including data converters, amplifiers, sensors, power management, and isolation products.

Application

ADuM1400ARW is a four-channel digital isolator. Typical application areas include:
- Isolated digital interfaces for microcontrollers and peripherals
- Industrial automation (PLCs, sensors, actuators)
- Motor drives and power electronics
- Data acquisition and instrumentation
- Automotive sensor interfaces and battery-management systems
- Medical equipment signal isolation
- Energy meters and smart power supplies

Equivalent

ADuM1400ARW is a 4‑channel iCoupler digital isolator. Equivalents from other vendors include:
- TI ISO784x family (4‑channel digital isolators)
- Silicon Labs Si86xx family (4‑channel digital isolators)
- NVE IL series (4‑channel digital isolators)
Also, other Analog Devices iCoupler parts (e.g., ADuM2400/2401) can serve as cross‑references if packaging/speed differ.
