ADUM1401CRWZ

The ADuM1401CRWZ is a quad-channel digital isolator from Analog Devices, built using iCoupler® technology. This component provides outstanding performance characteristics superior to traditional optocoupler devices by eliminating the need for LEDs and photodiodes. It offers four independent isolation channels with a high data rate of up to 90 Mbps (NRZ).

Key electrical specifications include 2500Vrms isolation voltage and high common-mode transient immunity of greater than 25 kV/µs. The isolator supports bidirectional communication and 3 V/5 V level translation. Power consumption is notably low, with a maximum of 1.0 mA per channel at 0-2 Mbps and 31 mA per channel at 90 Mbps when operating at 5V.

Designed for high-temperature operation up to 125°C, the ADuM1401CRWZ features precise timing characteristics, including a maximum pulse width distortion of 2 ns and channel-to-channel matching of 2 ns. It is available in a 16-lead SOIC wide body package, suitable for surface mount applications.

Applications for this digital isolator include general-purpose multichannel isolation, SPI interface/data converter isolation, RS-232/RS-422/RS-485 transceivers, industrial field bus isolation, and automotive systems.
