ADuM121N1WBRZ – 2-Channel Digital Isolator, 150 Mbps, CMTI, SOIC-8

The ADuM121N1WBRZ is a high-performance 2-channel digital isolator engineered using Analog Devices’ advanced iCoupler technology. By combining high-speed CMOS circuitry with a monolithic air-core transformer, this isolator delivers superior signal integrity, low latency and exceptional noise immunity compared to traditional optocouplers. Designed for demanding industrial and high-speed communication environments, the ADuM121N1WBRZ offers a maximum propagation delay of just 13 ns at 5 V and less than 3 ns pulse-width distortion, ensuring tight timing accuracy and reliable data transfer. With excellent channel-to-channel matching and robust protection against radiated and conducted noise, this isolator is ideal for motor control, power systems, isolated interfaces, data acquisition, and high-speed digital communication applications.
