ADUM231D1BRWZ-RL

Overview

The ADUM231D1BRWZ-RL is a robust digital isolator from Analog Devices, featuring three independent channels with a 2:1 input-to-output configuration. It utilizes magnetic coupling technology to provide electrical isolation rated at 5000 Vrms. The device supports data rates up to 150 Mb/s and exhibits a typical propagation delay of 7.2 ns. Operating on a supply voltage range of 1.7 V to 5.5 V, it draws a typical operating current of 8.8 mA. The component is housed in a 16-pin SOIC package and is designed for operation within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation via magnetic coupling technology
• Features unidirectional signal transmission across three channels
• Supports high-speed data communication up to 150 Mb/s
• Operates over an extended industrial temperature range

Applications

• General-purpose digital isolation in industrial systems
• Isolation for microcontroller peripheral interfaces
• Signal isolation in measurement and sensing equipment

Procurement Notes

Verify the specific suffix D1BRIZ or BRWZ against the manufacturer's official datasheet to confirm pinout and insulation ratings. Confirm moisture sensitivity level (MSL) requirements for surface mount assembly processes. Ensure the selected variant matches the required channel count and isolation voltage specifications for the target application design.

Selection Notes

Select this component when a 3-channel unidirectional isolator with 5000 Vrms capability is required. Consider the 150 Mb/s data rate limit and 7.2 ns propagation delay for timing-sensitive designs. Evaluate the 16-SOIC package dimensions for PCB layout constraints. Compare power consumption characteristics against alternative capacitive isolators if low standby current is critical.
