ADUM6422ABRNZ3

ADUM6422ABRNZ3 Description

The ADUM6422ABRNZ3 from Analog Devices Inc. is a high-performance, quad-channel digital isolator integrating 5kV RMS isolation with IsoPower® technology, enabling both signal and power isolation in a single package. Designed for general-purpose applications, it leverages magnetic coupling (iCoupler®) to deliver robust noise immunity and reliable data transmission at 100Mbps. Operating from 1.7V to 5.5V, it supports bidirectional logic-level translation across isolated domains. Its 5000Vrms isolation rating and 75kV/µs common-mode transient immunity (CMTI) make it ideal for harsh industrial environments. Packaged in a 28-lead SOIC tube, it complies with ROHS3 and REACH standards, ensuring environmental and regulatory compatibility.

ADUM6422ABRNZ3 Features

• Quad-Channel Isolation: Four unidirectional channels for signal isolation.
• Integrated Power Isolation: Eliminates the need for external DC-DC converters via IsoPower® technology.
• High-Speed Performance: 100Mbps data rate with 2.5ns rise/fall times and low 17ns propagation delay.
• Robust Noise Immunity: 75kV/µs CMTI and 5ns pulse width distortion ensure signal integrity in noisy environments.
