ADN4654BRWZ

ADN4654BRWZ Description

The ADN4654BRWZ from Analog Devices Inc. is a high-performance, dual-channel digital isolator leveraging magnetic coupling (iCoupler®) technology to provide robust 5kVrms isolation for LVDS (Low-Voltage Differential Signaling) applications. Designed for high-speed data transmission, it supports 1.25Gbps data rates with ultra-low propagation delay (4.5ns max) and fast rise/fall times (0.35ns typ). Operating from 2.375V to 2.625V, it ensures reliable signal integrity in noisy environments, featuring 25kV/µs common-mode transient immunity (CMTI). Packaged in a 20-pin SOIC tube, it is RoHS3 compliant and suitable for industrial, medical, and automotive systems requiring galvanic isolation.

ADN4654BRWZ Features

• Dual-Channel Unidirectional Isolation: Two isolated LVDS channels for unidirectional data transfer.
• High-Speed Performance: 1.25Gbps data rate with 0.35ns rise/fall times, ideal for time-sensitive applications.
• Robust Isolation: 5000Vrms reinforced isolation and 25kV/µs CMTI for EMI resilience.
• Low Power Consumption: Operates at 2.375V–2.625V, minimizing energy use in power-sensitive designs.
• Industry-Leading Reliability: iCoupler® technology eliminates optocoupler aging issues, offering long-term stability.
• Compact & Compliant: 20-SOIC package, REACH unaffected, and MSL 3 rated for extended shelf life.
