Product details

Channel direction — picking the right variant

With a 4/0 input configuration, all four channels on the ADUM6400ARWZ drive from Side 1 to Side 2. If your design needs bidirectional communication or more inputs on the secondary side, the family offers the ADUM6402ARWZ (2/2 split) and ADUM6403ARWZ (1/3 split) — same package, same isolation, same power output, just different channel direction counts. The pinout is consistent across the ADUM6400x variants, so swapping between them is a BOM-line change, not a board respin.

Isolation and transient immunity

The 5000 Vrms isolation rating covers reinforced-grade separation, suitable for medical patient-contact circuits, motor-drive phase-to-logic isolation, and grid-tied inverter communication. Common-mode transient immunity is rated at a minimum 25 kV/µs.

Lifecycle and sourcing

The ADUM6400ARWZ is listed as Active with ROHS3 compliance. There is no end-of-life notice or last-time-buy window, so it remains a safe choice for both new designs and production replenishment.

Frequently asked questions

Does ADUM6400ARWZ have isolated power?

Yes, the ADUM6400ARWZ integrates an isolated DC-DC converter (IsoPower®) on-chip, providing a regulated isolated output voltage without an external transformer.

What is the difference between ADUM6400 and ADUM6401?

The ADUM6400 has a 4/0 channel direction (all four channels from Side 1 to Side 2), while the ADUM6401 has a 3/1 split. Both share the same 5000 Vrms isolation, 1 Mbps data rate, and 16-SOIC package.

What is the replacement for ADUM6400ARWZ?

There is no direct replacement announced; the part remains active. For a higher-speed alternative in the same footprint, consider the ADUM6400CRWZ (25 Mbps). For a different channel-direction split, the ADUM6402ARWZ (2/2) or ADUM6403ARWZ (1/3) are pin-compatible.
