Product details

3750 Vrms isolation for industrial bus isolation

The ADUM1241ARSZ is a two-channel, unidirectional digital isolator from Analog Devices' iCoupler magnetic-coupling family. Its 3750 Vrms isolation rating suits it for breaking ground loops and providing safety isolation in industrial interfaces. The 2 Mbps data rate handles most UART and low-speed SPI links.

Active lifecycle — no last-time-buy scramble

ADI lists the ADUM1241ARSZ as Active. That means you can plan multi-year production runs without worrying about a forced last-time-buy window.

Package and temperature — shelf and board fit

Housed in a 20-lead SSOP (5.30 mm body width), surface-mount only. Store the reels dry — SSOP packages are MSL-sensitive, and a bake cycle before reflow adds a day to the build if the moisture barrier bag has been open past the floor-life window.

Frequently asked questions

Can ADUM1241ARSZ be used for I2C isolation?

The ADUM1241ARSZ has unidirectional channels (1/1 configuration), so it cannot directly handle the bidirectional SDA line of I2C without external circuitry. For I2C isolation, look at parts with bidirectional channel support or add discrete transistors to steer the data direction.

Is ADUM1241ARSZ compatible with a 3.3V supply?

Yes. It is not compatible with 5 V supplies.
