Overview

Description

ADUM251N1BRIZ is an Analog Devices iCoupler digital isolator in the ADuM family. It provides galvanic isolation between two independent power domains to safely transfer digital signals (for interfaces such as SPI, I2C, UART) across an isolation barrier. The device uses iCoupler technology (no opto components) for high-speed, low-power, bidirectional or multi-channel signal transfer, with compatible logic levels on both sides and RoHS-compliant packaging (BRIZ variant). Typical benefits include protection from ground loops and high-voltage transients, improved noise immunity, and easy integration into microcontroller or ASIC designs. Common applications are industrial automation, motor drives, medical devices, power supplies, and data-acquisition systems requiring isolation of digital interfaces. For exact specifications—isolation voltage, data rate, propagation delay, voltage rails, package details, and pinout—refer to the official ADI datasheet and product page.

Features

Here are the typical features of the ADuM251N1BRIZ (iCoupler digital isolator family):
- 2 independent bidirectional data channels using iCoupler technology
- 5 kV RMS galvanic isolation between input and output
- Separate primary and secondary supplies (VDD1 and VDD2), supports logic levels around 3.0–5.5 V
- High-speed data transfer (up to tens of Mbps; commonly cited around 25 Mbps, varies by variant)
- Fast propagation delay (typical on the order of a few to ~10 ns)
- High common-mode transient immunity (CMTI, typically tens of kV/µs)
- Low power consumption
- RoHS-compliant, lead-free package (e.g., compact 8-pin package)
- 100% production tested for isolation voltage and performance
Note: exact numbers depend on the specific device variant and operating conditions; consult the datasheet for precise specifications.

Package

16‑lead SOIC (surface‑mount) package; RoHS‑compliant.

Pinout

- Pin count: 8 pins (8‑lead package, BRIZ).
- Function: Analog Devices’ ADuM251N1BRIZ is a single‑channel isoSPI digital isolator, providing galvanic isolation between two sides (two isolated power rails) for a SPI/IsoSPI data path.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI)
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing ICs (including isolation and sensor products).

Application

ADUM251N1BRIZ is a high-speed, galvanically isolated digital isolator. It safely transfers digital signals between two ground-referenced domains, protecting low-voltage logic from high-voltage/noise and preventing ground loops. Typical applications: isolating microcontroller interfaces (SPI, I2C, UART) to high-voltage or noisy peripherals; industrial automation and PLC I/O; motor-drive and power-electronics interfaces; data acquisition/instrumentation; medical equipment safety isolation; automotive and battery-management systems.

Equivalent

Direct one-to-one equivalents are scarce. Closest cross-references for ADuM251N1BRIZ (digital isolator) include:
- TI ISO784x family (ISO7841/7842) two-channel digital isolators
- Silicon Labs Si86xx/Si862x two-channel digital isolators
- Analog Devices ADuM1250/1251/1252 (iCoupler, similar channel count)
Note: verify isolation voltage, propagation delay, supply range, pinout, and logic levels; there may be minor packaging differences.
