Digital Isolators

ADUM4402BRWZ Description

The ADUM4402BRWZ from Analog Devices Inc. is a high-performance, quad-channel digital isolator utilizing magnetic coupling (iCoupler®) technology. Designed for 5kVrms isolation, it ensures robust signal integrity in noisy environments. Operating at 3V to 5.5V, this unidirectional isolator supports 10Mbps data rates with minimal propagation delay (50ns max) and low pulse width distortion (3ns max). Its 25kV/µs common-mode transient immunity (CMTI) makes it ideal for industrial applications requiring high noise immunity. Packaged in a 16-SOIC tube, it is RoHS3 compliant and rated for MSL 1 (unlimited) shelf life.

ADUM4402BRWZ Features

• Quad-channel isolation: Four unidirectional channels (2 inputs/side) for bidirectional system designs.
• High-speed performance: 2.5ns rise/fall times and 10Mbps data rate ensure efficient signal transmission.
• Robust isolation: 5000Vrms reinforced isolation with magnetic coupling for superior noise rejection.
• Low distortion: 3ns max pulse width distortion maintains signal accuracy.
• Wide supply range: 3V–5.5V compatibility for flexible power supply designs.
• Industrial-grade reliability: 25kV/µs CMTI and REACH/ROHS3 compliance for harsh environments.

ADUM4402BRWZ Applications

• Industrial automation: Isolate PLCs, motor drives, and sensors in high-noise settings.
