ADUM131D1BRWZ-RL

Overview

The ADUM131D1BRWZ-RL is a triple-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 2:1 channel configuration with three channels operating at a data rate of 150 Mb/s. The device provides an insulation voltage of 3750 Vrms and supports a common-mode transient immunity of 75 kV/µs. Operating on a supply voltage range of 1.8 V to 5 V, it exhibits a typical propagation delay of 7.2 ns and operates within a temperature range of -40°C to +125°C. Packaged in a 16-SOIC surface-mount format.

Feature Summary

• Implements robust iCoupler magnetic coupling technology for high-speed digital isolation
• Provides unidirectional signal transmission across three independent channels
• Ensures safe system performance in noisy and harsh environments through high insulation voltage

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power management circuits with high-voltage noise rejection requirements

Procurement Notes

Verify the specific suffix 'D1' against official Analog Devices documentation to confirm the 2:1 channel configuration and 150 Mb/s data rate specifications. Ensure the reel packaging matches production requirements. Cross-reference the RoHS status and moisture sensitivity level with current datasheet revisions before finalizing procurement orders.

Selection Notes

Select this component when high-speed data rates up to 150 Mb/s are required alongside robust common-mode transient immunity of 75 kV/µs. The wide operating temperature range and low propagation delay make it suitable for demanding industrial applications where signal integrity and speed are critical constraints.

Part Context

This part belongs to the ADuM131D series of triple-channel digital isolators. It is designed based on Analog Devices' proprietary iCoupler technology, which integrates transformer-based isolation on-chip. The series offers various configurations to meet different channel count and speed requirements for general-purpose isolation needs.

Replacement Considerations

The ADUM131D1BRWZ is the tube-packaged equivalent of this reel version. For lower speed requirements, the ADUM1311 series offers similar functionality at 10 Mb/s. Verify pinout compatibility and electrical parameters before substituting with other isolator families.
