Description
ADuM251N1BRIZ is a one-channel digital isolator from Analog Devices’ iCoupler family. It provides galvanic isolation between the input side (VDD1) and the isolated output side (VDD2) to transfer a single digital signal without a direct electrical connection. The device uses iCoupler capacitive isolation technology (no opto components) for fast, reliable signal transfer with protection against voltage and transient events on the non-isolated side. Each side can be powered separately, enabling safe interfacing between low-voltage control circuitry and higher-voltage or noisy environments. Typical uses include isolated I/O, microcontroller-to-driver signaling, motor drives, sensors, PLCs, and other applications requiring a single isolated digital channel. The BRIZ suffix denotes RoHS-compliant, tape-and-reel packaging.
Features
ADUM251N1BRIZ is Analog Devices’ iCoupler digital isolator. Key features:
- Two independent uni-directional digital isolation channels across a galvanic barrier
- iCoupler technology (no optocouplers) for rugged, small, low‑cost isolation
- 5 kV RMS isolation (per IEC/IEC 61010) between input and output
- Separate input-side and output-side supply rails (logic-compatible, typically 2.7–5.5 V)
- High-speed, with very low propagation delay suitable for SPI, I2C, UART interfaces
- High common-mode transient immunity to withstand fast disturbances
- Low power consumption
- 8-pin package (BRIZ variant) with wide operating temperature
- Robust ESD protection on I/O pins
These make it suitable for isolating digital signals in microcontroller interfaces and mixed‑signal systems while maintaining safety and performance.

Pinout
- Pin count: 8 pins (8-pin package).
- Function: Digital isolator (iCoupler) with a single data channel, providing galvanic isolation between side 1 and side 2. Each side has its own supply/ground (VDD1/VSS1 and VDD2/VSS2). The A/D inputs on the primary side translate to the secondary side output with isolation.
