DESCRIPTION

· The ADuM1400/ADuM1401/ADuM1402 are quad-channel digital isolators utilizing iCoupler® technology.

· They combine high-speed CMOS and monolithic air core transformer technology for superior performance.

· These isolators eliminate common optocoupler issues like uncertain current transfer ratios and temperature effects.

· They operate with supply voltages from 2.7 V to 5.5 V, enabling voltage translation across the isolation barrier.

· Features include low pulse width distortion and tight channel-to-channel matching.

· A patented refresh feature ensures DC correctness without input logic transitions or power on one supply.

FEATURES

· Qualified for automotive applications with low power operation.

· Supports 5 V and 3 V operations with varying current consumption based on data rates.

· Capable of bidirectional communication and 3 V/5 V level translation.

· High temperature operation up to 125°C and data rates up to 90 Mbps.

· Features precise timing with maximum pulse width distortion and channel-to-channel matching of 2 ns.

· High common-mode transient immunity greater than 25 kV/μs.

· Comes in a 16-lead SOIC wide body package with RoHS-compliant models available.

APPLICATIONS

· Suitable for general-purpose multichannel isolation and SPI interface/data converter isolation.

· Ideal for RS-232/RS-422/RS-485 transceivers and industrial field bus isolation.

· Effective in automotive systems requiring robust isolation solutions.
