Description

The ADUM1200BRZ is a dual-channel digital isolator which is part of the ADuM120x series, based on Analog Devices' iCoupler® technology. This technology combines high-speed CMOS and monolithic transformer technology to offer superior performance compared to optocoupler devices. The ADUM1200BRZ is offered in a narrow-body SOIC 8-lead package and is designed for bidirectional communication, 3V/5V level translation, and high-temperature operation up to 105°C. It provides precise timing characteristics, with a maximum pulse-width distortion of 3ns and maximum channel-to-channel matching of 3ns. Additionally, it features high common-mode transient immunity at above 25 kV/µs.
