Digital Isolators

ADUM142D1BRWZ Description

The ADUM142D1BRWZ from Analog Devices Inc. is a high-performance, quad-channel digital isolator from the iCoupler® series, leveraging magnetic coupling technology for robust signal isolation. It provides 3750Vrms of reinforced isolation, making it suitable for applications requiring high-voltage separation. Operating from 1.7V to 5.5V, it supports bidirectional logic-level translation and delivers a 150Mbps data rate with minimal propagation delay (13ns max). Its unidirectional channel configuration ensures reliable signal integrity in noise-prone environments. Packaged in a 16-SOIC tube, this device is RoHS3 compliant and rated for MSL 3 (168 hours) moisture sensitivity.

ADUM142D1BRWZ Features

• High-Speed Performance: Achieves 150Mbps data rates with 2.5ns rise/fall times, ideal for fast digital interfaces.
• Superior Isolation: 3750Vrms isolation and 75kV/µs common-mode transient immunity (CMTI) ensure reliability in high-noise industrial systems.
• Low Power & Wide Voltage Range: Operates from 1.7V to 5.5V, enabling compatibility with low-power microcontrollers and mixed-voltage designs.
• Minimal Signal Distortion: Pulse width distortion <3ns and matched propagation delays (13ns max) preserve signal accuracy.
• Robust Packaging: 16-SOIC surface-mount package with REACH unaffected and EAR99/ECCN compliance for global use.
