Product details

Four-channel isolation with a 2/2 direction split

The Analog Devices ADUM3402ARWZ is a four-channel, unidirectional digital isolator from the iCoupler family. It uses magnetic coupling to provide galvanic isolation up to 2500 Vrms between the input and output sides.

1 Mbps signaling and propagation delay budget

Maximum data rate is 1 Mbps, with typical rise/fall time of 2.5 ns. Propagation delay is 100 ns max in both directions, and pulse-width distortion is 40 ns max.

Lifecycle and ordering

The part is ROHS3 compliant. The ADUM4401ARIZ offers 5000 Vrms isolation in a wider creepage package, at the cost of a different channel direction split (3/1).

Frequently asked questions

Is ADUM3402ARWZ compatible with 3.3V logic?

Yes. The inputs and outputs are rated for the supply voltage on their respective side, making it compatible with 3.3 V logic levels.
