概述

Description

ADuM4120ARIZ-RL is a 4-channel, galvanically isolated digital isolator from Analog Devices using iCoupler technology. It transfers four digital signals across an isolation barrier while keeping two power domains separate. It includes isoPower, allowing the isolated side to be powered from the primary-side supply (reducing external isolated regulators). The device supports 3.3V/5V logic on both sides, offers robust industrial-grade isolation, high common-mode transient immunity, and low propagation delay for fast signaling. Typical applications: isolating microcontrollers from high-voltage or noisy domains (motor drives, PLCs, sensors, data acquisition). The ARIZ suffix denotes packaging type (tape-and-reel, RoHS-compliant). For exact electrical specs and limits, refer to the datasheet.

Features

Key features of ADUM4120ARIZ-RL (4-channel digital isolator, iCoupler):
- 4 isolated data channels using iCoupler technology
- Reinforced isolation: 5 kV RMS (UL 1577) between input and output
- Independent dual-supply operation: VDD1 and VDD2 (3.0–5.5 V typical, suitable for 3.3 V/5 V logic)
- Data rate: up to about 25 Mbps per channel
- Propagation delay and channel skew designed for low-latency digital signaling
- High common-mode transient immunity (CMTI) to withstand fast transients
- Wide operating temperature: -40 °C to +125 °C
- ESD protection on I/O pins; robust operation in industrial environments
- RoHS-compliant, tape-and-reel packaging (ARIZ), 16-pin package variants
Note: for exact numbers (e.g., precise tPD, CMTI, and package options), please refer to the latest datasheet.

Package

ADuM4120ARIZ-RL uses a 16‑lead LFCSP (lead-frame chip-scale package), typically 3×3 mm, RoHS compliant, Tape & Reel.

Pinout

16 pins. It is a 4-channel galvanically isolated digital isolator (iCoupler) providing four isolated data paths between the primary (A) side and secondary (B) side, with separate VDD1/VDD2 and ground pins. The ARIZ package indicates a 16‑lead SOIC/related RoHS lead-free variant.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits and related components.

Application

ADUM4120ARIZ-RL is a 4-channel digital isolator for isolated SPI/I2C/UART data links. Typical applications:
- Industrial automation (PLCs, motor drives) requiring galvanic isolation
- Power electronics and inverter systems (solar, wind, EV battery management)
- Data acquisition and instrumentation in noisy/high-voltage environments
- Automotive/transportation electronics needing isolated controller communication
