ADUM5241ARZ

ADUM5241ARZ Description

The ADUM5241ARZ from Analog Devices Inc. is a high-performance, dual-channel digital isolator integrating magnetic coupling (iCoupler®) technology with isolated power (IsoPower®). Designed for 2.7V to 5.5V supply ranges, it delivers 2500Vrms isolation, making it ideal for applications requiring robust noise immunity and safety compliance. With a 1Mbps data rate, low propagation delay (70ns max), and 25kV/µs common-mode transient immunity (CMTI), it ensures reliable signal integrity in harsh environments. Packaged in an 8-pin SOIC, it is RoHS3 compliant and suitable for surface-mount assembly.
