Product details

What this iCoupler isolator is and where it goes

The ADUM3301ARWZ-RL is a 3-channel, unidirectional digital isolator from ADI's iCoupler magnetic-coupling family. It provides 2500Vrms isolation across a 16-SOIC wide-body package, with a 1Mbps data rate and 25kV/µs common-mode transient immunity. The supply range spans 3V to 5.5V, so it bridges 3.3V and 5V logic domains without extra level shifters.

The channel configuration is 2 inputs on side 1 and 1 input on side 2 — a 2/1 split that matches common isolated SPI patterns (SCLK, MOSI from the controller, MISO back) or a control-signal pair plus a single feedback line. All channels are unidirectional, so plan your data flow accordingly; a bidirectional bus like I2C needs a different isolator architecture.

Propagation delay and pulse-width distortion — timing budget factors

Maximum propagation delay is 100ns each way, with pulse-width distortion capped at 40ns. Rise and fall times are 2.5ns typical.

Frequently asked questions

What are the alternatives for ADUM3301ARWZ-RL?

Within the same iCoupler family, the ADUM3402ARWZ-RL offers four channels with a 2/2 input split, while the ADUM1310ARWZ-RL provides three channels all on one side (3/0) with a higher 3750Vrms isolation rating. Both are pin-compatible in the 16-SOIC wide-body footprint and share the same 1Mbps data rate and 25kV/µs transient immunity.

Is ADUM3301ARWZ-RL an equivalent to ADUM3301ARWZ?

The ADUM3301ARWZ-RL is the same device as the ADUM3301ARWZ, differing only in packaging — the -RL suffix denotes tape-and-reel format, while the base suffix typically indicates tube or tray. Electrical specifications are identical.
